Subject: drm/bridge: lt8713sx: avoid 64-bit division
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c196276f7809ac89743e6de61262c1b4b84f78d0;p=thirdparty%2Flinux.git

drm/bridge: lt8713sx: avoid 64-bit division

On 32-bit kernels, 64-bit integers cannot be passed to the division operator:

ld.lld-22: error: undefined symbol: __aeabi_uldivmod
>>> referenced by lontium-lt8713sx.c
>>>               drivers/gpu/drm/bridge/lontium-lt8713sx.o:(lt8713sx_firmware_store) in archive vmlinux.a

Since this is a constant number used to divide a size_t, just change the type
to that as well.
