Hello Takashi,

Commit eaa9b3a748539651f50e3a234c8854e1b42a839a introduced the following
uninitialized warning:

	sound/pci/hda/patch_realtek.c: In function 'set_capture_mixer':
	sound/pci/hda/patch_realtek.c:4928: warning: 'pin' is used uninitialized in this function
	sound/pci/hda/patch_realtek.c:4918: note: 'pin' was declared here

It appears indeed that 'pin' needs to be initialized to 0.
