[PATCH v4 07/21] media: vicodec: change variable name for the return value of v4l2_fwht_encode

[Dafna Hirschfeld <dafna3@gmail.com>]

v4l2_fwht_encode returns either an error code on
failure or the size of the compressed frame on
success. So change the var assigned to it from
'ret' to 'comp_sz_or_errcode' to clarify that.
