Subject: mmc: tmio_mmc: drop dma_sglen state variable
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3383433ce70613514593c940a2ae4e6ab19f2b28;p=linux-beck.git

mmc: tmio_mmc: drop dma_sglen state variable

This variable doesn't seem to be used for anything after the
other patches so just drop it.
