Subject: [PATCH 3/3] spi: spi-rspi: Drop redeclaring ret variable in qspi_transfer_in()
Date: Wed, 17 Nov 2021 01:05:27 +0000 [thread overview]
Message-ID: <20211117010527.27365-4-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20211117010527.27365-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
"ret" variable is already declared in qspi_transfer_in() at the
beginning of function, drop redeclaring ret in the if block, fixing
below:
spi-rspi.c: In function ‘qspi_transfer_in’:
spi-rspi.c:838:7: warning: declaration of ‘ret’ shadows a previous local
838 | int ret = rspi_dma_transfer(rspi, NULL, &xfer->rx_sg);
| ^~~
spi-rspi.c:835:6: note: shadowed declaration is here
835 | int ret;
Fixes: db30083813b55 ("spi: rspi: avoid uninitialized variable access")
