From 52150c78270db56ef5c0de0bf9d13d1d437d1236 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Wed, 1 Mar 2017 17:35:07 -0800 Subject: [PATCH] HID: usbhid: Use pr_ and remove unnecessary OOM messages Use a more common logging style and remove the unnecessary OOM messages as there is default dump_stack when OOM. Miscellanea: o Hoist an assignment in an if o Realign arguments o Realign a deeply indented if descendent above a printk Signed-off-by: Joe Perches Reviewed-by: Benjamin Tissoires Signed-off-by: Jiri Kosina --- drivers/hid/usbhid/hid-core.c | 16 +++++++--------- drivers/hid/usbhid/hid-quirks.c | 11 ++++------- 2 files changed, 11 insertions(+), 16 deletions(-) diff --git a/drivers/hid/usbhid/hid-core.c b/drivers/hid/usbhid/hid-core.c index b06fee1b8e47..9ef9c0837d95 100644 --- a/drivers/hid/usbhid/hid-core.c +++ b/drivers/hid/usbhid/hid-core.c @@ -1008,10 +1008,9 @@ static int usbhid_parse(struct hid_device *hid) return -EINVAL; } - if (!(rdesc = kmalloc(rsize, GFP_KERNEL))) { - dbg_hid("couldn't allocate rdesc memory\n"); + rdesc = kmalloc(rsize, GFP_KERNEL); + if (!rdesc) return -ENOMEM; - } hid_set_idle(dev, interface->desc.bInterfaceNumber, 0, 0); @@ -1081,8 +1080,8 @@ static int usbhid_start(struct hid_device *hid) if (hid->quirks & HID_QUIRK_FULLSPEED_INTERVAL && dev->speed == USB_SPEED_HIGH) { interval = fls(endpoint->bInterval*8); - printk(KERN_INFO "%s: Fixing fullspeed to highspeed interval: %d -> %d\n", - hid->name, endpoint->bInterval, interval); + pr_info("%s: Fixing fullspeed to highspeed interval: %d -> %d\n", + hid->name, endpoint->bInterval, interval); } /* Change the polling interval of mice and joysticks. */ @@ -1468,10 +1467,9 @@ static int hid_post_reset(struct usb_interface *intf) * the size of the HID report descriptor has not changed. */ rdesc = kmalloc(hid->dev_rsize, GFP_KERNEL); - if (!rdesc) { - dbg_hid("couldn't allocate rdesc memory (post_reset)\n"); + if (!rdesc) return -ENOMEM; - } + status = hid_get_class_descriptor(dev, interface->desc.bInterfaceNumber, HID_DT_REPORT, rdesc, hid->dev_rsize); @@ -1649,7 +1647,7 @@ static int __init hid_init(void) retval = usb_register(&hid_driver); if (retval) goto usb_register_fail; - printk(KERN_INFO KBUILD_MODNAME ": " DRIVER_DESC "\n"); + pr_info(KBUILD_MODNAME ": " DRIVER_DESC "\n"); return 0; usb_register_fail: diff --git a/drivers/hid/usbhid/hid-quirks.c b/drivers/hid/usbhid/hid-quirks.c index d6847a664446..9287ab03e117 100644 --- a/drivers/hid/usbhid/hid-quirks.c +++ b/drivers/hid/usbhid/hid-quirks.c @@ -237,10 +237,8 @@ static int usbhid_modify_dquirk(const u16 idVendor, const u16 idProduct, } q_new = kmalloc(sizeof(struct quirks_list_struct), GFP_KERNEL); - if (!q_new) { - dbg_hid("Could not allocate quirks_list_struct\n"); + if (!q_new) return -ENOMEM; - } q_new->hid_bl_item.idVendor = idVendor; q_new->hid_bl_item.idProduct = idProduct; @@ -306,10 +304,9 @@ int usbhid_quirks_init(char **quirks_param) &idVendor, &idProduct, &quirks); if (m != 3 || - usbhid_modify_dquirk(idVendor, idProduct, quirks) != 0) { - printk(KERN_WARNING - "Could not parse HID quirk module param %s\n", - quirks_param[n]); + usbhid_modify_dquirk(idVendor, idProduct, quirks) != 0) { + pr_warn("Could not parse HID quirk module param %s\n", + quirks_param[n]); } } -- 2.20.1
