2014-11-06m501fb: don't return zero on failure path in sm501fb_probe()Alexey Khoroshilov1-0/+1
If no framebuffers found, sm501fb_probe() breaks off initialization, deallocates sm501fb_info, but returns zero. As a result, use after free can happen in sm501fb_remove(). The patch adds -ENODEV as a return value in this case. Found by Linux Driver Verification project (linuxtesting.org).

2014-10-14video: fbdev: replace strnicmp with strncasecmpRasmus Villemoes1-2/+2
The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

In line with practice for module parameters, we're adding a build-time check that sysfs files aren't world-writable. Cc: Vincent Sanders <vince@simtec.co.uk> Cc: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-0/+2240
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
