* lib, net: make isodigit() public and use itAndy Shevchenko2013-04-293-2/+6

* argv_split(): teach it to handle mutable stringsOleg Nesterov2013-04-291-47/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | argv_split() allocates argv[count_argc(str)] array and assumes that it will find the same number of arguments later. This is obviously wrong if this string can be changed, say, by sysctl. With this patch argv_split() kstrndup's the whole string and does not split it, we simply replace the spaces with zeroes and keep the allocated memory in argv[-1] for argv_free(arg). We do not use argv[0] because: - str can be all-spaces or empty. In fact this case is fine, we could kfree() it before return, but: - str can have a space at the start, and we can not rely on kstrndup(skip_spaces(str)) because it can equally race if this string is mutable. Also, simplify count_argc() and kill the no longer used skip_arg().

* backlight: lp855x: move backlight mode platform dataKim, Milo2013-04-293-16/+15
| | | | | | | | | | | | | | | | | | The brightness of LP855x devices is controlled by I2C register or PWM input . This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe(). Move 'mode' from a header file to the driver private data structure, 'lp855 x'. And correlated code was replaced.

| | | | | | | | | | | | | | | | While doing with make W=1 gcc (gcc (GCC) 4.7.2 20121109 (Red Hat 4.7.2-8)) I found drivers/video/backlight/lp855x_bl.c: In function `lp855x_probe': drivers/video/backlight/lp855x_bl.c:342:35: warning: variable `mode' set but not used [-Wunused-but-set-variable] fixed by removing it as since its not used anywhere Signed-off-by: Devendra Naga <devendra.aaru@gmail.com> Acked-by: Milo Kim <milo.kim@ti.com> Cc: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* drivers/video/backlight/atmel-pwm-bl.c: add __init annotationJingoo Han2013-04-291-1/+1
| | | | | | | | | When platform_driver_probe() is used, bind/unbind via sysfs is disabled. Thus, __init/__exit annotations can be added to probe()/remove().

* drivers/video/backlight/atmel-pwm-bl.c: use module_platform_driver_probe()Jingoo Han2013-04-291-11/+1
| | | | | | | | | | Use the module_platform_driver_probe() macro which makes the code smaller and simpler.

* drivers/video/backlight/ep93xx_bl.c: remove incorrect __init annotationJingoo Han2013-04-291-1/+1
| | | | | | | | | | | When platform_driver_probe() is not used, bind/unbind via sysfs is enabled. Thus, __init/__exit annotations should be removed from probe()/remove().

* drivers/video/backlight/platform_lcd.c: remove unnecessary ifdefsJingoo Han2013-04-291-4/+2
| | | | | | | | | | When the macro such as SIMPLE_DEV_PM_OPS is used, there is no need to use '#ifdef CONFIG_PM' to prevent build error. Thus, this patch removes unnecessary ifdefs.
