[PATCH] drm/shmem-helper: Fix compile error

[Andi Shyti]

Commit 67b7836d4458 ("drm/shmem-helper: Switch to reservation
lock") removes the drm_gem_shmem_get_pages_locked() and
drm_gem_shmem_put_pages_locked().

But then commit ddddedaa0db9 ("drm/shmem-helper: Fix locking for
drm_gem_shmem_get_pages_sgt()") reintroduces it.

Somehow these two commits got mixed up and produce the following
compile error:

drivers/gpu/drm/drm_gem_shmem_helper.c: In function ‘drm_gem_shmem_get_pages_sgt_locked’:
drivers/gpu/drm/drm_gem_shmem_helper.c:651:15: error: implicit declaration of function ‘drm_gem_shmem_get_pages_locked’; did you mean ‘drm_gem_shmem_get_pages_sgt_locked’? [-Werror=implicit-function-declaration]
  651 |         ret = drm_gem_shmem_get_pages_locked(shmem);
      |               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |               drm_gem_shmem_get_pages_sgt_locked
drivers/gpu/drm/drm_gem_shmem_helper.c:673:9: error: implicit declaration of function ‘drm_gem_shmem_put_pages_locked’; did you mean ‘drm_gem_shmem_get_pages_sgt_locked’? [-Werror=implicit-function-declaration]
  673 |         drm_gem_shmem_put_pages_locked(shmem);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |         drm_gem_shmem_get_pages_sgt_locked

Remove the use of the *_locked() functions as it was intended in
the original patch.

Fixes: ddddedaa0db9 ("drm/shmem-helper: Fix locking for drm_gem_shmem_get_pages_sgt()")

Hi,

I don't know if this issue has already been addressed, if so it
hasn't reached yet drm-tip.
