usb: storage: alauda: Remove set but unchecked variable
The return value of alauda_get_media_status() hasn't been checked since the driver's inception back in 2005. If nothing have gone wrong/been detected until this point, it's probably safe to just remove the variable. Fixes the following W=1 kernel build warning(s): drivers/usb/storage/alauda.c: In function ‘alauda_check_media’: drivers/usb/storage/alauda.c:456:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable] 456 | int rc; | ^~ Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Daniel Drake <dsd@gentoo.org> Cc: usb-storage@lists.one-eyed-alien.net Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20200703174148.2749969-20-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
