drm/gma500: Fix BUG: sleeping function called from invalid context errors
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: Fix BUG: sleeping function called from invalid context errors
gma_crtc_page_flip() was holding the event_lock spinlock while calling
crtc_funcs->mode_set_base() which takes ww_mutex.
The only reason to hold event_lock is to clear gma_crtc->page_flip_event
on mode_set_base() errors.
Instead unlock it after setting gma_crtc->page_flip_event and on
errors re-take the lock and clear gma_crtc->page_flip_event it
it is still set.
This fixes the following WARN/stacktrace:
