From 5a78401623740c892868d5929b33f5cda8fe819e Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 18 Mar 2014 14:11:26 +0100 Subject: [PATCH] mfd: sec-core: Fix uninitialized 'regmap_rtc' on S2MPA01 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Initialize the 'regmap_rtc' on S2MPA01 to some sane value. Sane at least for S5M87X chipsets, not S2MPS/S2MPA but it won't be used because rtc-s5m driver does not support S2MPA01. This fixes following error: drivers/mfd/sec-core.c:342:45: warning: ‘regmap_rtc’ may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Krzysztof Kozlowski Acked-by: Sachin Kamat Signed-off-by: Lee Jones --- drivers/mfd/sec-core.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/drivers/mfd/sec-core.c b/drivers/mfd/sec-core.c index 91405e94cfee..1cf27521fff4 100644 --- a/drivers/mfd/sec-core.c +++ b/drivers/mfd/sec-core.c @@ -298,6 +298,13 @@ static int sec_pmic_probe(struct i2c_client *i2c, switch (sec_pmic->device_type) { case S2MPA01: regmap = &s2mpa01_regmap_config; + /* + * The rtc-s5m driver does not support S2MPA01 and there + * is no mfd_cell for S2MPA01 RTC device. + * However we must pass something to devm_regmap_init_i2c() + * so use S5M-like regmap config even though it wouldn't work. + */ + regmap_rtc = &s5m_rtc_regmap_config; break; case S2MPS11X: regmap = &s2mps11_regmap_config; -- 2.20.1
