[PATCH 2/3] Blackfin SPI Driver: Fix peripheral pins initialization bug in SPI probe

From: Bryan Wu
Date: Wed Mar 26 2008 - 06:28:56 EST


From: Vitja Makarov <vitja.makarov@xxxxxxxxx>

Fix bug in SPI probe: first initialize peripheral pins,
and just after register spi master device. This fixes
problems with SPI drivers built-in kernel.
