2021-08-21rtw88: refine the setting of rsvd pages for different firmwareChin-Yen Lee1-23/+17
The original setting of rsvd pages is compilcated and lead to error for connecting to AP after resuming from pno mode. We refine the setting based on different firmware and the link state to avoid it.

2021-08-21rtw88: use read_poll_timeout instead of fixed sleepChin-Yen Lee1-5/+16
In current wow flow, driver calls rtw_wow_fw_start and sleep for 100ms, to wait firmware finish preliminary work and then update the value of WOWLAN_WAKE_REASON register to zero. But later firmware will start wow function with power-saving mode, in which mode the value of WOWLAN_WAKE_REASON register is 0xea. So driver may get 0xea value and return fail. We use read_poll_timeout instead to check the value to avoid this issue.

2021-08-21rtw88: 8822ce: set CLKREQ# signal to low during suspendChin-Yen Lee2-0/+34
We find the power sequence of system suspend flow don't meet the criteria when using 8822CE-VR chip by rfe-type 6, because the reference clock form host is sometimes late. To avoid the behavoir, we keep CLKREQ# signal to low during suspend to make sure the reference clock arrival in time.

2021-08-21rtl8xxxu: disable interrupt_in transfer for 8188cu and 8192cuChris Chiu1-2/+2
There will be crazy numbers of interrupts triggered by 8188cu and 8192cu module, around 8000~10000 interrupts per second, on the usb host controller. Compare with the vendor driver source code, it's mapping to the configuration CONFIG_USB_INTERRUPT_IN_PIPE and it is disabled by default. Since the interrupt transfer is neither used for TX/RX nor H2C commands. Disable it to avoid the excessive amount of interrupts for the 8188cu and 8192cu module which I only have for verification.

2021-08-21mwifiex: usb: Replace one-element array with flexible-array memberGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.

The patch that would first try the board-specific firmware had a bug because the fallback would not be called: the asynchronous interface is used meaning request_firmware_nowait() returns 0 immediately. Harden the firmware loading like this: - If we cannot build an alt_path (like if no board_type is specified) just request the first firmware without any suffix, like in the past. - If the lookup of a board specific firmware fails, we get a NULL fw in the async callback, so just try again without the alt_path from a dedicated brcm_fw_request_done_alt_path callback. - Drop the unnecessary prototype of brcm_fw_request_done. - Added MODULE_FIRMWARE match for per-board SDIO bins, making userspace tools to pull all the relevant firmware files.

Now, after being exposed for ten years to refactoring, general tree-wide changes and various janitor clean-up, it is really time to delete the driver for good. This was discovered as part of a checkpatch evaluation, investigating all reports of checkpatch's WARNING:OBSOLETE check. p54 replaces prism54 so users should be unaffected.

Example: a 4330 device with the OF board compatible is "samsung,gavini". We will first try "brcmfmac4330-sdio.samsung,gavini.bin" then "brcmfmac4330-sdio.bin" if that does not work.

2021-07-26net: ixp4xx_hss: use dma_pool_zallocJason Wang1-2/+1
The dma_pool_zalloc combines dma_pool_alloc/memset. Therefore, the dma_pool_alloc/memset can be replaced with dma_pool_zalloc which is more compact. Signed-off-by: Jason Wang <wangborong@cdjrlc.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-07-26net: mhi: Improve MBIM packet countingRichard Laing2-7/+11
Packets are aggregated over the MBIM link and currently the MHI net device will count each aggregated packet rather then the actual packets themselves. If a protocol handler module is specified, use that to count the packets rather than directly in the MHI net device. This is in line with the behaviour of the USB net cdc_mbim driver.

This patch is to fix it by accessing skb_cb->bytes_read earlier than calling tsk_advance_rx_queue().
