Subject: [SSB] Initialise dma_mask for SSB_BUSTYPE_SSB devices
X-Git-Tag: v2.6.27-rc8~4^2
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=ac82da3381fc663dbda31612a0bff60bc41676a3;p=linux-2.6-omap-h63xx.git

[SSB] Initialise dma_mask for SSB_BUSTYPE_SSB devices

For SSB_BUSTYPE_SSB type devices, we need to initialize dma_mask using
coherent_dma_mask so that calls to dma_set_mask() succeed.

It fixes the regression on the b44 driver introduced by commit
f225763a7d6c92c4932dbd528437997078496fcc
