If a user provides a shortened string to match a device to the sysfs i2c interface it will match on the first string that contains that string prefix. for example: echo a 0x68 > /sys/bus/i2c/devices/i2c-2/new_device will match as3711, as3722, and ak8975 incorrectly. Correct this by using sysfs_streq to match the string exactly Signed-off-by: Kieran Bingham <kieran@xxxxxxxxxxx> --- Changes from v7 - strncasecmp usage converted to sysfs_streq drivers/i2c/i2c-core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/i2c/i2c-core.c b/drivers/i2c/i2c-core.c index c338c8f3b3db..8b93a262e237 100644 --- a/drivers/i2c/i2c-core.c +++ b/drivers/i2c/i2c-core.c @@ -1810,7 +1810,7 @@ i2c_of_match_device_sysfs(const struct of_device_id *matches, else name++; - if (!strncasecmp(client->name, name, strlen(client->name))) + if (sysfs_streq(client->name, name)) return matches; } -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
