[PATCH] media: rkisp1: uapi: change hist_bins array type from __u16 to __u32

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

 



Each entry in the array is a 20 bits value composed of 16
bits unsigned integer and 4 bits fractional part. So the
type should change to __u32.
