[PATCH AUTOSEL 5.10 011/116] media: atomisp-ov2680: Fix ov2680_set_fmt() clobbering the exposure

From: Sasha Levin
Date: Mon Jan 17 2022 - 22:47:46 EST


From: Hans de Goede <hdegoede@xxxxxxxxxx>

[ Upstream commit 4492289c31364d28c2680b43b18883385a5d216c ]

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().
