2019-04-25zd1211rw: use struct_size() helperGustavo A. R. Silva1-2/+1
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace code of the following form: sizeof(struct usb_req_write_regs) + count * sizeof(struct reg_data) with: struct_size(req, reg_writes, count) This code was detected with the help of Coccinelle.

2018-06-27zd1211rw: use irqsave() in USB's complete callbackSebastian Andrzej Siewior1-9/+12
The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

2017-08-10zd1211rw: constify usb_device_idArvind Yadav1-1/+1
usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by <linux/usb.h> work with const usb_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-03-22zd1211rw: fix NULL-deref at probeJohan Hovold1-0/+3
Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory beyond the endpoint array should a malicious device lack the expected endpoints.
