Subject: OMAP1: McBSP: fix build break for non-multi-OMAP1 configs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e7916740bb76379bcde4ce0317259acff8f89f53;p=linux-beck.git

OMAP1: McBSP: fix build break for non-multi-OMAP1 configs

Commit 3cf32bba8ca0e0052ca41d74d455a5805b7fea85 ("OMAP: McBSP: Convert
McBSP to platform device model") breaks compilation with non-multi-OMAP1
configs:

  CC      arch/arm/mach-omap1/mcbsp.o
arch/arm/mach-omap1/mcbsp.c: In function 'omap1_mcbsp_init':
arch/arm/mach-omap1/mcbsp.c:384: warning: dereferencing 'void *' pointer
arch/arm/mach-omap1/mcbsp.c:387: error: invalid use of void expression
arch/arm/mach-omap1/mcbsp.c:390: warning: dereferencing 'void *' pointer
arch/arm/mach-omap1/mcbsp.c:393: error: invalid use of void expression

Fix by avoiding NULL dereferences.
