Subject: [PATCH master 3/5] imx-bbu-nand-fcb: suppress compiler warning about uninitialized use
Date: Mon,  3 Jan 2022 12:57:16 +0100	[thread overview]
Message-ID: <20220103115718.1723730-4-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220103115718.1723730-1-a.fatoum@pengutronix.de>

fw_orig_len is selectively initialized in read_firmware_all. In case
it's left uninitialized, fw_orig will keep it's initial value of NULL.
fw_orig is checked before fw_orig_len use, so there is no use of an
uninitialized variable in practice, but GCC 11.1.1 warns about it
anyway. Give it an initial value of 0 to silence the warning.
