To: linux-omap; +Cc: Tony Lindgren, Jarkko Nikula
This 'legacy' OMAP2420 McBSP2 muxing code is currently broken after recent
conversion to new mux code. The omap_mcbsp_request calling this code is
usually called after booting whereas the omap_mux_init_signal is __init
marked so null pointer dereference would occur.
Fix this by removing the muxing code and let the bootloader or board file to
do it if necessary. Remove also omap2_mcbsp_ops as there is no use for it.

This is v2. No any other changes than based on top of commit 451fd82 that
came from ASoC tree for 2.6.36 and which causes conflicts with v1.
