[alsa-devel] [PATCH] soc at91 minor bug fixes

Found these two bugs while browsing through the code.
The first one is a cut-n-paste bug, instead of disabling the clock when request_irq()
fails, it enabled it once more.
The second one fixes a debug printout, AT91_SSC_IER is write only, AT91_SSC_IMR is 
readable (the printed string actually says imr).

Frank Mandarino was busy so he asked me to send these to this list.
