[PATCH] drm/radeon/trinity_dpm: fix a memleak in trinity_parse_power_table

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

 



The rdev->pm.dpm.ps allocated by kcalloc should be freed in every
following error-handling path. However, in the error-handling of
rdev->pm.power_state[i].clock_info the rdev->pm.dpm.ps is not freed,
resulting in a memleak in this function.
