Subject: [PATCH] media: atomisp-ov2680: Fix ov2680_set_fmt() clobbering the exposure
Git-commit: 4492289c31364d28c2680b43b18883385a5d216c
Patch-mainline: v5.17-rc1
References: git-fixes
Now that we restore the default or last user set exposure setting on
power_up() there is no need for the registers written by ov2680_set_fmt()
to write to the exposure register.
Not doing so fixes the exposure always being reset to the value from
the res->regs array after a set_fmt().
