Subject: typhoon: memory corruptor on big-endian if TSO is enabled
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8cc085c7aceb78d26d0a5355e111b2330f089161;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

typhoon: memory corruptor on big-endian if TSO is enabled

txlo_dma_addr should be host-endian; we pass it to typhoon_tso_fill(),
which does arithmetics on it, converts to l-e and passes it to card.
Unfortunately, we forgot le32_to_cpu() when initializing it from
face->txLoAddr, which sits in shared memory and is little-endian.
