Subject: [PATCH 3/3] staging: rtlwifi: simplify logical operation
Date: Wed, 23 Aug 2017 15:22:53 +0200	[thread overview]
Message-ID: <20170823132337.517466-3-arnd@arndb.de> (raw)
In-Reply-To: <20170823132337.517466-1-arnd@arndb.de>

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.
