[PATCH] drm/bridge: ps8640: Fix size mismatch warning w/ len

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

 



After commit 26195af57798 ("drm/bridge: ps8640: Drop the ability of
ps8640 to fetch the EDID"), I got an error compiling:

  error: comparison of distinct pointer types
  ('typeof (len) *' (aka 'unsigned int *') and
   'typeof (msg->size) *' (aka 'unsigned long *'))
  [-Werror,-Wcompare-distinct-pointer-types]

Fix it by declaring the `len` as size_t.

Sorry for sending this hot on the heels of the other patch, but for
some reason that other patch compiled fine for me until I picked it
back to my downstream tree. I'll see if I can track down why. In any
case, as soon as I see a Reviewed-by tag I'll land this.
