X-Git-Tag: Ubuntu-5.4-5.4.0-11.14~7901^2~709 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=a71c8e9b8efc30459d4dbae9dff90fba46f46c63;p=mirror_ubuntu-focal-kernel.git staging: emxx_udc: Add comment for spinlock_t definition. Members of nbu2ss_udc structure can change device state, maintain completion state and control driver. Also provide access to read and write to register. Hence, exclusive access to nbu2ss_udc is required. The lock variable of type spinlock_t guarantees the exclusive access and protects it. In this patch, comment is added for spinlock_t definition, to fix the following checkpatch issue: CHECK: spinlock_t definition without comment Signed-off-by: Varsha Rao Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/staging/emxx_udc/emxx_udc.h b/drivers/staging/emxx_udc/emxx_udc.h index 789bfb97143c..78c08e15a1f9 100644 --- a/drivers/staging/emxx_udc/emxx_udc.h +++ b/drivers/staging/emxx_udc/emxx_udc.h @@ -567,7 +567,7 @@ struct nbu2ss_udc { struct usb_gadget_driver *driver; struct platform_device *pdev; struct device *dev; - spinlock_t lock; + spinlock_t lock; /* Protects nbu2ss_udc structure fields */ struct completion *pdone; enum ep0_state ep0state;
