Subject: [PATCH] staging: rtlwifi: simplify logical operation
Git-commit: 03fef6c5c2296ee6d43f59af57973e82c229039c
Patch-mainline: v4.14-rc1
References: FATE#326887
gcc notices a very complicated way to check a value
for being equal to one, and warns about it:
Drivers/staging/rtlwifi/btcoexist/halbtc8822b1ant.c: In function 'halbtc8822b1ant_set_ext_ant_switch':
drivers/staging/rtlwifi/btcoexist/halbtc8822b1ant.c:2105:9: error: '~' on a boolean expression [-Werror=bool-operation]
~switch_polatiry_inverse :
^
drivers/staging/rtlwifi/btcoexist/halbtc8822b1ant.c:2105:9: note: did you mean to use logical not?
~switch_polatiry_inverse :
^
This simplifies this expression to make it more readable
and to make gcc happy.
