Subject: [PATCH AUTOSEL 5.10 15/36] media: rkisp1: stats: remove a wrong cast to u8

From: Dafna Hirschfeld <dafna.hirschfeld@...labora.com>

[ Upstream commit a76f8dc8be471028540df24749e99a3ec0ac7c94 ]

hist_bins is an array of type __u32. Each entry represent
a 20 bit fixed point value as documented inline.
The cast to u8 when setting the values is wrong. Remove it.
