[PATCH i-g-t] test/kms_plane_lowres: Fix display_commit_mode() so it returns the crc

[PATCH i-g-t] test/kms_plane_lowres: Fix display_commit_mode() so it returns the crc

[Arkadiusz Hiler]

Compiler complained on crc_lowres and crc_hires2 being uninitialized
and indeed, display_commit_mode() seems to have intention of retruning
the value through the parameter that is only a single pointer.

This couses only the local copy of the pointer, the one inside
display_commit_mode(), to be overwritten.

Let's fix that!

Also add missing hires crc comparison (M. Kahola).

[PATCH i-g-t v2] test/kms_plane_lowres: Fix display_commit_mode() so it returns the crc

[Arkadiusz Hiler]

Compiler complained on crc_lowres and crc_hires2 being uninitialized
and indeed, display_commit_mode() seems to have intention of retruning
the value through the parameter that is only a single pointer.

This couses only the local copy of the pointer, the one inside
display_commit_mode(), to be overwritten.

Let's fix that!

Also add missing hires crc comparison (M. Kahola).

v2: make display_commit_mode return just the last CRC

[PATCH v3 i-g-t] test/kms_plane_lowres: Fix display_commit_mode() so it returns the crc

[Maarten Lankhorst]

From: Arkadiusz Hiler <arkadiusz.hiler@intel.com>

Compiler complained on crc_lowres and crc_hires2 being uninitialized
and indeed, display_commit_mode() seems to have intention of retruning
the value through the parameter that is only a single pointer.

This couses only the local copy of the pointer, the one inside
display_commit_mode(), to be overwritten.

Let's fix that!

Also add missing hires crc comparison (M. Kahola).

v2: make display_commit_mode return just the last CRC
v3: Don't do memory allocations, it's hard. (Maarten)

So sorry, didn't like the memory allocations, hope this works.. else I'll commit v2..
