drm/bridge: ps8640: Fix size mismatch warning w/ len
[ Upstream commit
35ba6bd582cf926a082296b7e9a876ec81136cb1 ]
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.
The above error only shows up on downstream kernels without commit
d03eba99f5bf ("minmax: allow min()/max()/clamp() if the arguments have
the same signedness."), but since commit
26195af57798 ("drm/bridge:
ps8640: Drop the ability of ps8640 to fetch the EDID") is a "Fix" that
will likely be backported it seems nice to make it easy. ...plus it's
more correct to declare `len` as size_t anyway.
Fixes:
