Subject: [PATCH] spi/bcm63xx: Move default clock configuration to kill compiler warning
Date: Mon, 9 Nov 2015 10:28:50 +0100 [thread overview]
Message-ID: <1447061330-19152-1-git-send-email-geert@linux-m68k.org> (raw)
drivers/spi/spi-bcm63xx.c: In function ‘bcm63xx_spi_setup_transfer’:
drivers/spi/spi-bcm63xx.c:207: warning: ‘clk_cfg’ may be used uninitialized in this function
While this is a false positive, it can easily be avoided by selecting
the default clock configuration first.
