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

[Shuah Khan]

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 | }

Hi Shuah,

You're the third person to send this patch recently but it was fixed on
Aug 2 in staging-next in commit 05344a1d2ea7 ("media: atomisp: restore
missing 'return' statement").  What tree are you working against?  It
seems like it needs to be backported somewhere.

regards,
dan carpenter

I am working on Linux 5.15 - should have checked staging next though before
sending the patch :)
