fbdev: fix cea_modes array size

2015-08-20T07:20:11+00:00

CEA defines 64 modes, indexed from 1 to 64. modedb has cea_modes arrays, which contains 64 entries. However, the code uses the CEA indices directly, i.e. the first mode is at cea_modes[1]. This means the array is one too short. This does not cause references to uninitialized memory as the code in fbmon only allows indexes up to 63, and the cea_modes does not contain an entry for the mode 64 so it could not be used in any case. However, the code contains a check 'if (idx > ARRAY_SIZE(cea_modes)', and while that check is a no-op as at that point idx cannot be >= 63, it upsets static checkers. Fix this by increasing the cea_array size to be 65, and change the code to allow mode 64. Signed-off-by: Tomi Valkeinen Reported-by: Dan Carpenter

video: fbdev: Check Standard Timing against DMT

2015-01-15T11:33:41+00:00

Add the VESA Display Monitor Timing (DMT) table. During parsing of Standard Timings, it compare the 2 byte STD code with DMT to see what the VESA mode should be. If there is no entry in the vesa_modes table or no match found, it fallsback to the GTF timings. Signed-off-by: David Ung Signed-off-by: Tomi Valkeinen

video/fb: Propagate error code from failing to unregister conflicting fb

2013-12-18T00:56:13+00:00

If we fail to remove a conflicting fb driver, we need to abort the loading of the second driver to avoid likely kernel panics.

fb: make fp_get_options name argument const

drm_get_connector_name now returns a const value, which causes the following compilation warning: drivers/gpu/drm/drm_fb_helper.c: In function ‘drm_fb_helper_parse_command_line’: drivers/gpu/drm/drm_fb_helper.c:127:3: warning: passing argument 1 of ‘fb_get_options’ discards ‘const’ qualifier from pointer target type [enabled by default] In file included from drivers/gpu/drm/drm_fb_helper.c:35:0: include/linux/fb.h:627:12: note: expected ‘char *’ but argument is of type ‘const char *’ As fb_get_options uses its name argument as read only, make it const. This fixes the aforementioned compilation warning.
