2017-05-24rsi: Add host interface operations as separate structure.Prameela Rani Garnepudi1-1/+8
Host interface operations are currently function pointers in rsi_hw structure. As more host interface operations are going to be introduced, separate structure is added for these for convenience.

2017-05-24rsi: Handle usb multi-byte write failure case properlyPrameela Rani Garnepudi1-4/+5
In function usb_write_register_multiple, if any intermediate block transfer is failed, further operations should be terminated. 'else' is removed, as there is no significance for it after return.

2017-05-24rsi: use macros in USB specific codePrameela Rani Garnepudi1-6/+9
For USB vendor read and write operations new macros added to avoid redundant usage of long or'ed macros. Also for timeouts standard USB macros are used.

2017-05-24rsi: Changes in USB read and write operationsPrameela Rani Garnepudi1-3/+3
USB read and write registers maximum size is limited 2^16. More than this size is not used in the driver. Signed-off-by: Prameela Rani Garnepudi <prameela.j04cs@gmail.com> Signed-off-by: Amitkumar Karwar <amit.karwar@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2014-07-01rsi: fix memory leaks and error handling in rsi_91x_usbAlexey Khoroshilov1-20/+38
The patch fixes a couple of issues: - absence of deallocation of rsi_dev->rx_usb_urb[0] in the driver; - potential NULL pointer dereference because of lack of checks for memory allocation success in rsi_init_usb_interface(). By the way, it makes rsi_probe() returning error code instead of 1 and fixes comments regarding returning values. Found by Linux Driver Verification project (linuxtesting.org).

2014-06-19rsi: Use module_usb_driverAlexey Khoroshilov1-27/+1
module_usb_driver eliminates the boilerplate and makes the code simpler, in addition to the fact currently rsi_module_init() ignores usb_deregister() error.
