We got a compile warning shows below:

drivers/net/wireless/marvell/mwifiex/sdio.c: In function
'mwifiex_sdio_remove':
drivers/net/wireless/marvell/mwifiex/sdio.c:377:6: warning: variable
'ret' set but not used [-Wunused-but-set-variable]

Per the code, it didn't check if mwifiex_sdio_read_fw_status
finish successfully. We should at least check the return of
mwifiex_sdio_read_fw_status, otherwise the following check of
firmware_stat and adapter->mfg_mode is pointless as the device
is probably dead.

I don't see that warning, any ideas why? My compiler:

gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

I was using gcc-arm-eabi-4.8- , but it doesn't matter.

Could you add W=1 to compile the code, for instance, "make W=1  -j32"
