This function is used by dev_get_regmap() to retrieve a regmap for the specified device. If the device has more than one regmap, the name parameter can be used to specify one.
The code here uses a pointer comparison to check for equal strings. This however will probably always fail, as the regmap->name is allocated via kstrdup_const() from the regmap's config->name. Fix this by using strcmp() instead. Signed-off-by: Marc Kleine-Budde <[email protected]> --- Hey, I stumbled over this by accident. AFAICS there's no-one on the kernel making use of the "name" parameter. regrads, Marc drivers/base/regmap/regmap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/base/regmap/regmap.c b/drivers/base/regmap/regmap.c index 06a796821e8b..795a62a04022 100644 --- a/drivers/base/regmap/regmap.c +++ b/drivers/base/regmap/regmap.c @@ -1364,7 +1364,7 @@ static int dev_get_regmap_match(struct device *dev, void *res, void *data) /* If the user didn't specify a name match any */ if (data) - return (*r)->name == data; + return !strcmp((*r)->name, data); else return 1; } -- 2.27.0
