2017-05-24rsi: Add host interface operations as separate structure.Prameela Rani Garnepudi
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 Garnepudi
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 Garnepudi
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 Garnepudi
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 Khoroshilov
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 Khoroshilov
module_usb_driver eliminates the boilerplate and makes the code simpler, in addition to the fact currently rsi_module_init() ignores usb_deregister() error.
