misc: genwqe: card_base: Remove set but unused variable 'rc'
Variable 'rc' hasn't been checked since the driver's inception in 2013. If it hasn't caused any issues since then, it's unlikely to in the future. Let's take it out for now. Fixes the following W=1 kernel build warning(s): drivers/misc/genwqe/card_base.c: In function ‘genwqe_health_check_stop’: /home/lee/projects/linux/kernel/drivers/misc/genwqe/card_base.c:1046:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable] 1046 | int rc; | ^~ Cc: Michael Jung <mijung@gmx.net> Cc: Michael Ruettger <michael@ibmra.de> Cc: Frank Haverkamp <haver@linux.ibm.com> Cc: Joerg-Stephan Vogt <jsvogt@de.ibm.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Reviewed-by: Frank Haverkamp <haver@linux.ibm.com> Link: https://lore.kernel.org/r/20200701085853.164358-17-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
