'patch_regs' cannot be used uninitialized in wm8994_device_init(), because 'patch_regs' was already guarded by 'regmap_patch'. Thus, that's a bogus warning.
Without this patch, the build warning happens as below: drivers/mfd/wm8994-core.c: In function 'wm8994_i2c_probe': drivers/mfd/wm8994-core.c:595:7: warning: 'patch_regs' may be used uninitialized in this function [-Wuninitialized] drivers/mfd/wm8994-core.c:408:14: note: 'patch_regs' was declared here Signed-off-by: Jingoo Han <[email protected]> --- drivers/mfd/wm8994-core.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/mfd/wm8994-core.c b/drivers/mfd/wm8994-core.c index 803e93f..97e929e 100644 --- a/drivers/mfd/wm8994-core.c +++ b/drivers/mfd/wm8994-core.c @@ -405,7 +405,7 @@ static int wm8994_device_init(struct wm8994 *wm8994, int irq) struct regmap_config *regmap_config; const struct reg_default *regmap_patch = NULL; const char *devname; - int ret, i, patch_regs; + int ret, i, patch_regs = 0; int pulls = 0; if (dev_get_platdata(wm8994->dev)) { -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
