Subject: serial: mfd: Staticize local symbols
X-Git-Tag: upstream/snapshot3+hdmi~4060^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9baaa6747e84b078e42b1a6d17088049b5320167;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

serial: mfd: Staticize local symbols

These local symbols are used only in this file.
Fix the following sparse warnings:

drivers/tty/serial/mfd.c:296:6: warning: symbol 'hsu_dma_tx' was not declared. Should it be static?
drivers/tty/serial/mfd.c:343:6: warning: symbol 'hsu_dma_start_rx_chan' was not declared. Should it be static?
drivers/tty/serial/mfd.c:389:6: warning: symbol 'hsu_dma_rx' was not declared. Should it be static?
drivers/tty/serial/mfd.c:1186:17: warning: symbol 'serial_hsu_pops' was not declared. Should it be static?
