X-Git-Tag: v2.6.37-rc1~60^2~3^2~318
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9bed00f20dc9f2e86b1834a5a30648f5728a51f8;p=profile%2Fivi%2Fkernel-x86-ivi.git

staging: west bridge, block driver change for partition support

This patch fixes an error in the block driver wherein multiple
partitions in an mmc card were not detected correctly due to
incorrect alloc_disk arguments.
