Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation.

Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

2019-12-18rsi: add missing endpoint sanity checksJohan Hovold1-2/+10
The driver expects at least one bulk-in endpoint when in "wifi-alone" operating mode and two bulk-in endpoints otherwise, and would otherwise fail to to submit the corresponding bulk URB to the default pipe during probe with a somewhat cryptic message: rsi_91x: rsi_rx_urb_submit: Failed in urb submission rsi_91x: rsi_probe: Failed in probe...Exiting RSI-USB WLAN: probe of 2-2.4:1.0 failed with error -8 The current endpoint sanity check looks broken and would only bail out early if there was no bulk-in endpoint but at least one bulk-out endpoint. Tighten this check to always require at least one bulk-in and one bulk-out endpoint, and add the missing sanity check for a Bluetooth bulk-in endpoint when in a BT operating mode.

2019-10-04mac80211: simplify TX aggregation startJohannes Berg1-2/+1
There really is no need to make drivers call the ieee80211_start_tx_ba_cb_irqsafe() function and then schedule the worker if all we want is to set a bit. Add a new return value (that was previously considered invalid) to indicate that the driver is immediately ready for the session, and make drivers use it. The only drivers that remain different are the Intel ones as they need to negotiate more with the firmware.

2019-09-03rsi: fix a double free bug in rsi_91x_deinit()Hui Peng1-1/+0
`dev` (struct rsi_91x_usbdev *) field of adapter (struct rsi_91x_usbdev *) is allocated and initialized in `rsi_init_usb_interface`. If any error is detected in information read from the device side, `rsi_init_usb_interface` will be freed. However, in the higher level error handling code in `rsi_probe`, if error is detected, `rsi_91x_deinit` is called again, in which `dev` will be freed again, resulting double free. This patch fixes the double free by removing the free operation on `dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also used in `rsi_disconnect`, in that code path, the `dev` field is not (and thus needs to be) freed. This bug was found in v4.19, but is also present in the latest version of kernel. Fixes CVE-2019-15504.

2019-08-06rsi: fix for sdio reset card issueGanapathi Kondraju1-10/+7
Issue: While removing and inserting the driver module, observed driver loading is not successful. Root cause: Card is not resetted completely without issuing cmd5. Fix: Issued cmd5 properly. Signed-off-by: Ganapathi Kondraju <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2019-08-06rsi: fix for sdio interface setup in 9116Ganapathi Kondraju1-4/+4
Issue: RS-9116 Card is not responding after firmware got loaded. Root cause: After firmware got loaded, we need to reset the program counter and few device specific registers. Those registers were not resetted properly. Fix: Properly resetting those registers. Signed-off-by: Ganapathi Kondraju <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2019-07-26mac80211: pass the vif to cancel_remain_on_channelEmmanuel Grumbach1-1/+2

Explicitly return constants instead of variable (and rely on it to be explicitly initialized), if the value is supposed to be fixed anyways.

2019-05-28rsi: Properly initialize data in rsi_sdio_ta_resetNathan Chancellor1-7/+14
When building with -Wuninitialized, Clang warns: drivers/net/wireless/rsi/rsi_91x_sdio.c:940:43: warning: variable 'data' is uninitialized when used here [-Wuninitialized] put_unaligned_le32(TA_HOLD_THREAD_VALUE, data); ^~~~ drivers/net/wireless/rsi/rsi_91x_sdio.c:930:10: note: initialize the variable 'data' to silence this warning u8 *data; ^ = NULL 1 warning generated. Using Clang's suggestion of initializing data to NULL wouldn't work out because data will be dereferenced by put_unaligned_le32. Use kzalloc to properly initialize data, which matches a couple of other places in this driver.

Till software bootloader ready state, communication with device is common for 9113 and 9116. Hence moved that part of firmware loading to separate function rsi_prepare_fw_load().
