From 2a54e845f6e5069666e1749bd952abdc0413910d Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 2 May 2017 22:33:02 +0900 Subject: [PATCH] ASoC: hisilicon: localize functions without external linkage A driver for hi6210 sound interface on hi6220 boards includes some functions which has no external linkage. These functions should have static qualifier. This commit adds the qualifier to localize the functions. This issue is detected by sparse: hi6210-i2s.c:100:5: warning: symbol 'hi6210_i2s_startup' was not declared. Should it be static? hi6210-i2s.c:178:6: warning: symbol 'hi6210_i2s_shutdown' was not declared. Should it be static? hi6210-i2s.c:527:27: warning: symbol 'hi6210_i2s_dai_init' was not declared. Should it be static?
