Subject: [PATCH] media: atomisp: restore missing 'return' statement

From: Arnd Bergmann <arnd@...db.de>

The input_system_configure_channel_sensor() function lost its final
return code in a previous patch:

drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.c: In function 'input_system_configure_channel_sensor':
drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.c:1649:1: error: control reaches end of non-void function [-Werror=return-type]

Restore what was there originally.

Fixes: 728a5c64ae5f ("media: atomisp: remove dublicate code")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
