Subject: [PATCH] media: atomisp: fix control reaches end of non-void function error

Fix the following build error with -Werror=return-type enabled. Fix
input_system_configure_channel_sensor() to return status when control
reaches the end.

drivers/staging/media/atomisp/pci/hive_isp_css_common/host/input_system.o
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]
 1649 | }
