[ Upstream commit 52282163dfa651849e905886845bcf6850dd83c2 ]
This commit is effectively already in 5.4. Confusingly there were two versions of this upstream:
52282163dfa6 ("drm/panfrost: Add missing check for pfdev->regulator") c90f30812a79 ("drm/panfrost: Add missing check for pfdev->regulator")
It got merged both through a -fixes branch and through the normal merge window. The two copies caused a bad merge in mainline and this was effectively reverted in commit 603e398a3db2 ("drm/panfrost: Remove NULL check for regulator").
c90f30812a79 is included in v5.4 so should already be in any v5.4.y release.
Have I mentioned this month just how much I hate the way the DRM tree handles stable patches like this? This kind of fallout is a pain for stable maintainers, I dred every time I see a drm patch tagged for stable.
But we've been over this all before :(
Another example is:
29cd13cfd762 ("drm/v3d: Fix memory leak in v3d_submit_cl_ioctl") 0d352a3a8a1f ("drm/v3d: don't leak bin job if v3d_job_init fails.")
Two fixes for a memory leak were merged so now it's a double free. I sent a patch on Jan 10 but no one responded.
