From 073b50bccbbf99a3b79a1913604c656d0e1a56c9 Mon Sep 17 00:00:00 2001 From: Jason Gerecke Date: Fri, 16 Aug 2019 11:54:26 -0700 Subject: HID: wacom: Fix several minor compiler warnings Addresses a few issues that were noticed when compiling with non-default warnings enabled. The trimmed-down warnings in the order they are fixed below are: * declaration of 'size' shadows a parameter * '%s' directive output may be truncated writing up to 5 bytes into a region of size between 1 and 64 * pointer targets in initialization of 'char *' from 'unsigned char *' differ in signedness * left shift of negative value Signed-off-by: Jason Gerecke Reviewed-by: Aaron Armstrong Skomra Signed-off-by: Jiri Kosina --- drivers/hid/wacom_sys.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'drivers/hid/wacom_sys.c') diff --git a/drivers/hid/wacom_sys.c b/drivers/hid/wacom_sys.c index 53bddb50aeba..602219a8710d 100644 --- a/drivers/hid/wacom_sys.c +++ b/drivers/hid/wacom_sys.c @@ -88,7 +88,7 @@ static void wacom_wac_queue_flush(struct hid_device *hdev, } static int wacom_wac_pen_serial_enforce(struct hid_device *hdev, - struct hid_report *report, u8 *raw_data, int size) + struct hid_report *report, u8 *raw_data, int report_size) { struct wacom *wacom = hid_get_drvdata(hdev); struct wacom_wac *wacom_wac = &wacom->wacom_wac; @@ -149,7 +149,8 @@ static int wacom_wac_pen_serial_enforce(struct hid_device *hdev, if (flush) wacom_wac_queue_flush(hdev, &wacom_wac->pen_fifo); else if (insert) - wacom_wac_queue_insert(hdev, &wacom_wac->pen_fifo, raw_data, size); + wacom_wac_queue_insert(hdev, &wacom_wac->pen_fifo, + raw_data, report_size); return insert && !flush; } @@ -2176,7 +2177,7 @@ static void wacom_update_name(struct wacom *wacom, const char *suffix) { struct wacom_wac *wacom_wac = &wacom->wacom_wac; struct wacom_features *features = &wacom_wac->features; - char name[WACOM_NAME_MAX]; + char name[WACOM_NAME_MAX - 20]; /* Leave some room for suffixes */ /* Generic devices name unspecified */ if ((features->type == HID_GENERIC) && !strcmp("Wacom HID", features->name)) { -- cgit v1.2.3
