From 4dde99bd32fc3f61f7c2b602a78f1627a118e450 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 9 Nov 2015 10:28:50 +0100 Subject: spi/bcm63xx: Move default clock configuration to kill compiler warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
