2022-05-09dm integrity: fix error code in dm_integrity_ctr()Dan Carpenter
The "r" variable shadows an earlier "r" that has function scope. It means that we accidentally return success instead of an error code. Smatch has a warning for this: drivers/md/dm-integrity.c:4503 dm_integrity_ctr() warn: missing error code 'r' Fixes: 7eada909bfd7 ("dm: add integrity target") Cc: stable@vger.kernel.org Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@kernel.org>

2022-05-09ath11k: reset 11d state in process of recoveryWen Gong
When doing simulate_fw_crash operation periodically with a short interval time such as 10 seconds, it is easy happened WMI command timed out for WMI_SCAN_CHAN_LIST_CMDID in ath11k_reg_update_chan_list(). log: [42287.610053] ath11k_pci 0000:01:00.0: wmi command 12291 timeout [42287.610064] ath11k_pci 0000:01:00.0: failed to send WMI_SCAN_CHAN_LIST cmd [42287.610073] ath11k_pci 0000:01:00.0: failed to perform regd update : -11 Note that this issue does not occur with a longer interval such as 20 seconds. The reason the issue occurs with a shorter interval is the following steps: 1) Upon initial boot, or after device recovery, the initial hw scan plus the 11d scan will run, and when 6 GHz support is present, these scans can take up to 12 seconds to complete, so ath11k_reg_update_chan_list() is still waiting the completion of ar->completed_11d_scan. 2) If a simulate_fw_crash operation is received during this time, those scans do not complete, and ath11k_core_pre_reconfigure_recovery() complete the ar->completed_11d_scan, then ath11k_reg_update_chan_list() wakeup and start to send WMI_SCAN_CHAN_LIST_CMDID, but firmware is crashed at this moment, so wmi timed out occur. To address this issue, reset the 11d state during device recovery so that WMI_SCAN_CHAN_LIST_CMDID does not timed out for short interval time such as 10 seconds.

Similarly to the horkage flags, introduce the force_lflag_onoff() macro to define struct ata_force_param entries of the force_tbl array that allow turning on or off a link flag using the libata.force boot parameter. To be consistent with naming, the macro force_lflag() is renamed to force_lflag_on().

2022-05-09mtd: spi-nor: support eon en25qh256a variantLeon M. George
This patch allows accessing the upper 16m on the A variant (EN25QH256A) of the EN25QH256 that shares same JEDEC ID. Without this patch, addr_with is detected to be '4' but the read_opcode is a plain READ (supporting only 3 byte addresses). Setting PARSE_SFDP is enough to detect the read_opcode READ_4B on the A variant. READ_4B is not available on the no-A variant. Both variants support 4-byte address mode (spi_nor_set_4byte_addr_mode) but that is prone to breaking on unexpected reboots if the reset pin isn't connected (broken-flash-reset). The no-A variant supports a 'high bank latch mode' that affects read, program, and erase commands - similar to the extended address register (EAR). The HBL bit is manipulated using the ENHBL (0x67) and EXHBL (0x98) opcodes. Should it become necessary to distinguish the two variants in the future, the A variant sets the SNOR_HWCAPS_READ_1_1_4 SFDP param - the no-A variant doesn't. Tested with and without fast read on the A variant only. Signed-off-by: Leon M.

2022-05-09net: wwan: t7xx: Device deep sleep lock/unlockHaijun Liu
Introduce the mechanism to lock/unlock the device 'deep sleep' mode. When the PCIe link state is L1.2 or L2, the host side still can keep the device is in D0 state from the host side point of view. At the same time, if the device's 'deep sleep' mode is unlocked, the device will go to 'deep sleep' while it is still in D0 state on the host side.

2022-05-09net: wwan: t7xx: Introduce power managementHaijun Liu
Implements suspend, resumes, freeze, thaw, poweroff, and restore `dev_pm_ops` callbacks. From the host point of view, the t7xx driver is one entity. But, the device has several modules that need to be addressed in different ways during power management (PM) flows. The driver uses the term 'PM entities' to refer to the 2 DPMA and 2 CLDMA HW blocks that need to be managed during PM flows. When a dev_pm_ops function is called, the PM entities list is iterated and the matching function is called for each entry in the list.

2022-05-09net: wwan: t7xx: Add data path interfaceHaijun Liu
Data Path Modem AP Interface (DPMAIF) HIF layer provides methods for initialization, ISR, control and event handling of TX/RX flows. DPMAIF TX Exposes the 'dmpaif_tx_send_skb' function which can be used by the network device to transmit packets. The uplink data management uses a Descriptor Ring Buffer (DRB). First DRB entry is a message type that will be followed by 1 or more normal DRB entries. Message type DRB will hold the skb information and each normal DRB entry holds a pointer to the skb payload. DPMAIF RX The downlink buffer management uses Buffer Address Table (BAT) and Packet Information Table (PIT) rings. The BAT ring holds the address of skb data buffer for the HW to use, while the PIT contains metadata about a whole network packet including a reference to the BAT entry holding the data buffer address. The driver reads the PIT and BAT entries written by the modem, when reaching a threshold, the driver will reload the PIT and BAT rings.
