Subject: alim15x3: remove redundant m5229_revision check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=99149a485958ada512eafc34fe36a80cb63fa56c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

alim15x3: remove redundant m5229_revision check

init_dma_ali15x3() guarantees that hwif->dma_base will never be set for
m5229_revision < 0x20 so remove redundant m5229_revision >= 0x20 check from
init_hwif_common_ali15x3().

While at it remove incorrect comment.
