From 03fef6c5c2296ee6d43f59af57973e82c229039c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 23 Aug 2017 15:22:53 +0200 Subject: staging: rtlwifi: simplify logical operation 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.
