Subject[PATCH net-next] net: qlcnic: remove unused variable 'val' in qlcnic_83xx_cam_unlock()
Date
Fixes the following W=1 kernel build warning(s):

drivers/net/ethernet/qlogic/qlcnic/qlcnic_83xx_hw.c:661:6: warning:
variable 'val' set but not used [-Wunused-but-set-variable]
661 | u32 val;
| ^~~

After commit 7f9664525f9c ("qlcnic: 83xx memory map and HW access
routines"), variable 'val' is never used in qlcnic_83xx_cam_unlock(), so
removing it to avoid build warning.
