Subject: OMAP: DSS2: DSI: remove unused function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4b6b7fa2d3677d1d86780c73fe2284147713e3b1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

OMAP: DSS2: DSI: remove unused function

dsi_reset_tx_fifo() was not used. Furthermore, OMAP errata states that
TX FIFO flush is not functional, so the function wouldn't even have
worked.
