In the future, the main board for this 9g45 series will be the AT91SAM9M10G45-EK (I choose this last name for the board file). Simple drivers are enabled in _devices and board- files.

This doesn't make much sense to encode the pointer in documentation as it prevents proper C type checking from occurring and can easily allow people to use the wrong pointer type. So convert the argument type to an explicit struct cn_msg pointer. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The vc_resize() allocated buffer would then get lost by vc_allocate() allocating a fresh one. Use vc_resize() only for actual resizing to close the leak. Set the dimensions manually only in initialization mode to remove the redundant setting in resize mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent he loop counter is of type 'unsigned char' and it should count to 128. The compiler will incorrectly decide that a trivial loop like this: unsigned char i, ... for (i = 0; i < 128; i++) { .. is endless, and will compile it to a single instruction that just branches to itself. This was triggered by the addition of '-fno-strict-overflow', and we could play games with compiler versions and go back to '-fwrapv' instead, but the trivial way to avoid it is to just make the loop induction variable be an 'int' instead. Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure for digging through assembler differences and finding it.
