[libav-devel] [PATCH] Add unconditional return statement to yuva420_rgb32_MMX() / yuva420_bgr32_MMX().

[Diego Biurrun]

When HAVE_7REGS was not defined these functions had an empty body
causing the following warnings during compilation.
In file included from libswscale/x86/yuv2rgb_mmx.c:58:
libswscale/x86/yuv2rgb_template.c: In function ‘yuva420_rgb32_MMX’:
libswscale/x86/yuv2rgb_template.c:412: warning: no return statement in function 
returning non-void
libswscale/x86/yuv2rgb_template.c: In function ‘yuva420_bgr32_MMX’:
libswscale/x86/yuv2rgb_template.c:457: warning: no return statement in function 
returning non-void
