* TTY: ircomm: fix DTR being raised on hang upJohan Hovold2013-04-121-1/+1
| | | | | | | | | | | | Make sure to check ASYNC_INITIALISED before raising DTR when waking up from blocked open in ircomm_tty_block_til_ready. Currently DTR could get raised at hang up as a blocked process would raise DTR unconditionally before checking for hang up and returning.

* tty: serial/samsung: fix modular buildArnd Bergmann2013-04-112-3/+5
| | | | | | | | | | There are a few bugs in the samsung serial driver when built as a loadable module, which makes the console code unavailable, as well as giving no access to the 'printascii' early debug function.

* tty: serial/samsung: make register definitions globalArnd Bergmann2013-04-115-284/+274
| | | | | | | | | | | | | | | | | | | | | | | | | The registers for the Samsung S3C serial port are currently defined in the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h file, which is not visible to multiplatform capable drivers. Unfortunately, it is not possible to move the file into a more local place as we should normally try to, because the same registers may be used in one of four places: * In the driver itself * In platform-independent ARM code for early debug output * In platform_data definitions * In the Samsung platform power management code I have also found no way to logically split out a platform_data file, other than possibly move everything into include/linux/platform_data, which also felt wrong. The only part of this file that makes sense to keep specific to the s3c24xx platform are the virtual and physical addresses defined here, which are needed in no other location.

| | | | | | | | | | | | With the common clock interface, there is no way to provide the "clock_source" sysfs attribute for the samsung serial ports.

* tty: Fix race condition if flushing tty flip buffersPeter Hurley2013-04-091-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Ilya Zykov identified in his patch 'PROBLEM: Race condition in tty buffer's function flush_to_ldisc()', a race condition exists which allows a parallel flush_to_ldisc() to flush and free the tty flip buffers while those buffers are in-use. For example, CPU 0 | CPU 1 | CPU 2 | flush_to_ldisc() | | grab spin lock | tty_buffer_flush() | | flush_to_ldisc() wait for spin lock | | wait for spin lock | if (!test_and_set_bit(TTYP_FLUSHING)) | | while (next flip buffer) | | ... | | drop spin lock | grab spin lock | | if (test_bit(TTYP_FLUSHING)) | | set_bit(TTYP_FLUSHPENDING) | receive_buf() | drop spin lock | | | | grab spin lock | | if (!test_and_set_bit(TTYP_FLUSHING)) | | if (test_bit(TTYP_FLUSHPENDING)) | | __tty_buffer_flush() CPU 2 has just flushed and freed all tty flip buffers while CPU 1 is transferring data from the head flip buffer. The original patch was rejected under the assumption that parallel flush_to_ldisc() was not possible. Because of necessary changes to the workqueue api, work items can execute in parallel on SMP. This patch differs slightly from the original patch by testing for a pending flush _after_ each receive_buf(), since TTYP_FLUSHPENDING can only be set while the lock is dropped around receive_buf().

The cause of this is the fix for this warning: drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init] In this chunk of the commit: @@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = { /* totalwidth */ 1135, /* sqwidth */ 944, /* vdelay */ 0x20, - /* sheight */ 576, - /* videostart0 */ 23) /* bt878 (and bt848?) can capture another line below active video. */ - .cropcap.bounds.height = (576 + 2) + 0x20 - 2, + /* sheight */ (576 + 2) + 0x20 - 2, + /* videostart0 */ 23) },{ .v4l2_id = V4L2_STD_NTSC_M | V4L2_STD_NTSC_M_KR, .name = "NTSC", Which replaces the overriding of cropcap.bounds.height initialization outside of the CROPCAP macro (which also initializes it), with passing a different sheight value to the CROPCAP macro. There are 2 problems with this warning fix: 1) The sheight value is used twice in the CROPCAP macro, and the old code only changed one resulting value. 2) The old code increased the .cropcap.bounds.height value (and did not touch the .cropcap.defrect.height value at all) by 2, where as the fixed code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2 to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so now is done twice for .cropcap.bounds.height, and also is applied to .cropcap.defrect.height where it should not be applied at all. This patch fixes this by adding an extraheight parameter to the CROPCAP entry and using it for the PAL entry.

| | * | [media] fimc-lite: Initialize 'step' field in fimc_lite_ctrl structureShaik Ameer Basha2013-03-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v4l2_ctrl_new() uses check_range() for control range checking. This function expects 'step' value for V4L2_CTRL_TYPE_BOOLEAN type control. If 'step' value doesn't match to '1', it returns -ERANGE error. This patch adds the default .step value to 1.

This was because the detach path issued a BLKRRPART to clean up partitions if LO_FLAGS_PARTSCAN was set, meaning that the partitions were auto scanned on attach. Replace this BLKRRPART with code that unconditionally cleans up partitions on detach instead. Signed-off-by: Phillip Susi <psusi@ubuntu.com> Modified by Jens to export delete_partition().

There is also one performance fix - which is to allocate pages for requests when the driver loads - instead of doing it per request
