[PATCH][V3] drm/i915/guc: fix GEM_BUG_ON check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The check for level being less than zero always false because flags
is currently unsigned and can never be negative. Fix this by making
level a s32.

Detected by CoverityScan, CID#1468363 ("Macro compares unsigned to 0")

Fixes: cb5d64e9f13e ("drm/i915/guc: Allow user to control default GuC logging")
Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx>
