Subject: [PATCH\ net] rtw88: fix fw dump support detection
Date: Mon, 26 Oct 2020 22:22:55 +0100	[thread overview]
Message-ID: <20201026212323.3888550-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

clang points out a useless check that was recently added:

drivers/net/wireless/realtek/rtw88/fw.c:1485:21: warning: address of array 'rtwdev->chip->fw_fifo_addr' will always evaluate to 'true' [-Wpointer-bool-conversion]
        if (!rtwdev->chip->fw_fifo_addr) {
            ~~~~~~~~~~~~~~~^~~~~~~~~~~~

Apparently this was meant to check the contents of the array
rather than the address, so check it accordingly.

Fixes: 0fbc2f0f34cc ("rtw88: add dump firmware fifo support")
