Subject: [PATCH net-next 06/11] rtlwifi: fix -Wpointer-sign warning
Date: Mon, 26 Oct 2020 22:29:53 +0100 [thread overview]
Message-ID: <20201026213040.3889546-6-arnd@kernel.org> (raw)
In-Reply-To: <20201026213040.3889546-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
There are thousands of warnings in a W=2 build from just one file:
drivers/net/wireless/realtek/rtlwifi/rtl8821ae/table.c:3788:15: warning: pointer targets in initialization of 'u8 *' {aka 'unsigned char *'} from 'char *' differ in signedness [-Wpointer-sign]
Change the types to consistently use 'const char *' for the
strings.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
