[RFC PATCH 04/10] PCMCIA: soc_common: push socket probe down into SoC specific support
Russell King
rmk at arm.linux.org.uk
Sun Oct 4 11:09:02 EDT 2009
Move the individual socket probing and initialization down into the
SoC specific support files, thereby allowing soc_common_drv_pcmcia_probe
to be eliminated. soc_common.c now no longer deals with distinct groups
of sockets.
