drm/gma500: Fix possible out of bounds read

2016-06-08T01:23:40+00:00

commit 7ccca1d5bf69fdd1d3c5fcf84faf1659a6e0ad11 upstream. Fix possible out of bounds read, by adding missing comma. The code may read pass the end of the dsi_errors array when the most significant bit (bit #31) in the intr_stat register is set. This bug has been detected using CppCheck (static analysis tool).

gma500: remove annoying deprecation warning

2016-04-04T19:38:46+00:00

In commit e45708976aea ("drm/dp-helper: Move the legacy helpers to gma500") the legacy i2c helpers were moved to the only remaining user of them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus() was marked deprecated and started warning about its remaining use. It's now been a year and a half of annoying warning, and apparently nobody cares enough about gma500 to try to move it along to the more modern models. Get rid of the warning - if even the gma500 people don't care enough, then they should certainly not spam other innocent developers with a warning that might hide other, much more real issues.

gma500: clean up an excessive and confusing helper

2016-02-08T09:07:09+00:00

This is a left over from the great clean ups in the past. It's confusing as it returns an int, yet has one caller that never uses it. The caller already has all the right private variables local so the entire function can be replaced by a simple if call.

drm/gma500: remove helper function

2016-02-08T09:03:17+00:00

We were getting build warning about: drivers/gpu/drm/gma500/mdfld_dsi_output.c:407:2: warning: initialization from incompatible pointer type The callback to dpms was pointing to a helper function which had a return type of void, whereas the callback should point to a function which has a return type of int. On closer look it turned out that we do not need the helper function since if we call drm_helper_connector_dpms() directly, the first check that drm_helper_connector_dpms() does is: if (mode == connector->dpms) Signed-off-by: Sudip Mukherjee Link: http://patchwork.freedesktop.org/patch/msgid/1454393155-13142-1-git-send-email-sudipm.mukherjee@gmail.com Acked-by: Patrik Jakobsson Signed-off-by: Daniel Vetter
