Hi,

There's a mutex lock deadlock in i915 that only affects 5.4, but was fixed in 5.5. Normally, I would send a backport of the fix from 5.5, but the patch set that fixes the deadlock involves massive changes that are neither feasible nor desirable for backporting [1][2][3]. Therefore, I've made a small patch that only addresses the deadlock specifically for 5.4.

This paragraph needs to go into the patch itself, otherwise just looking at that doesn't make any sense.

And you do not need a cover letter for a single patch.

Please fix up and resend.

thanks,
