* rtlwifi: Modify rtl_pci_init to return 0 on successJohn W. Linville2012-02-091-3/+3
| | | | | | | | | | | | Fixes problem where caller would think routine succeeded when it failed leading to divide by zero panic. (This also reverts an earlier attempt, commit 42bc0c97 "rtlwifi: Return correct failure code on error". -- JWL) Signed-off-by: Simon Graham <simon.graham@virtualcomputer.com> Acked-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rtlwifi: Return correct failure code on errorSimon Graham2012-02-081-1/+1
| | | | | | | | | Callers of rtl_pci_init expect zero to be returned on error. Returning the error code leads to, amongst other things, divide by zero panics attempting to use the ring size that is set to zero.

| | | | | | | | | | | | | The comment states that the field is only used for rt61pci and rt73usb. However, it is now used by rt2800pci and rt2800usb as well, so the comment is not correct anymore.

* rt2x00: Introduce concept of driver data in struct rt2x00_dev.Gertjan van Wingerde2012-02-082-0/+24
| | | | | | | | | | | | | We are getting more and more fields in struct rt2x00_dev that are specific to one or two of the low-level drivers. Instead of putting these fields inside the main structure and thus clobbering all low-level drivers with these fields, introduce the concept of driver data inside struct rt2x00_dev, whose size is indicated by the low-level driver and which can be populated by the low-level driver.

* mwifiex: update correct dtim_period in dump_station()Amitkumar Karwar2012-02-064-9/+10
| | | | | | | | | | | | | | | | | | | Earlier we were using dtim period extracted from scan response buffer provided by FW in scan operation. But it is observed that sometimes the buffer doesn't contain dtim period tlv, and wrong value (0) was sent to user space. After association FW will start listening to beacon frames of connected AP and store dtim period. Therefore we can get it from FW in dump_station() instead of using wrong value obtained in scanning. Redundant code after adapting new approach for dtim period is also removed in this patch.

Also don't pci_set_drvdata(pdev, NULL) until just before disabling the PCI device. Functions called by rtl_deinit_core(hw) may eventually need the context (when its actually implemented).
