2013-07-24mwifiex: correction in mwifiex_check_fw_status() return statusAmitkumar Karwar1-2/+0
For PCIe cards, when wrong firmware is downloaded, firmware is failed to be ready in 10 seconds. We should return an error at this point. But currently we are sending first command to firmware. As expected firmware doesn't respond to this command and command timeout occurs. This patch fixes the problem by removing unnecessary 'ret' variable modifications in "if (ret) {" block.

2013-07-24mwifiex: reduce firmware poll retriesAmitkumar Karwar2-4/+0
After downloading the firmware, firmware status is checked by reading a register. Polling interval is 100 msecs. Therefore 100 retries means the status is checked for 10 secs which is more than sufficient for firmware to get ready. This patch removes 1000 retries macro usage, because 100secs time is not practical.

Clear the data pointer stored in USB interface structure in this handler. This helps to return from mwifiex_usb_disconnect() if driver deinitialization is already performed while handling an error path for mwifiex_usb_probe(). USB8797 card gets enumerated twice. First enumeration is for firmware download and second enumeration expects firmware initialization. mwifiex_usb_probe() always takes care of deinitialization for first enumeration after firmware download.
