This patch introduces a build error in sound/soc/fsl/imx-pcm-fiq.c:
sound/built-in.o: In function `imx_pcm_fiq_free':
last.c:(.text+0x2aca8): undefined reference to `mxc_set_irq_fiq'
sound/built-in.o: In function `imx_pcm_fiq_init':
last.c:(.text+0x2b1a4): undefined reference to `mxc_set_irq_fiq'
last.c:(.text+0x2b200): undefined reference to `mxc_set_irq_fiq'
make[1]: *** [vmlinux] Error 1
make: *** [sub-make] Error 2

This could be fixed with the following patch:
