From 8fcf7a6569790fb5be4e5fa7d1a9f10734c6e8d8 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 7 Jan 2019 17:23:20 +0100 Subject: serial: sh-sci: Make RX/TX DMA function names consistent Most RX/TX-specific DMA functions are prefixed with "sci_dma_[rt]x_". Rename the exceptions to increase consistency.
