2021-02-10net: octeontx2: Fix the confusion in buffer alloc failure pathKevin Hao
Pavel pointed that the return of dma_addr_t in otx2_alloc_rbuf/__otx2_alloc_rbuf() seem suspicious because a negative error code may be returned in some cases. For a dma_addr_t, the error code such as -ENOMEM does seem a valid value, so we can't judge if the buffer allocation fail or not based on that value. Add a parameter for otx2_alloc_rbuf/__otx2_alloc_rbuf() to store the dma address and make the return value to indicate if the buffer allocation really fail or not.

2021-02-10net: mhi: Add mbim protoLoic Poulain
MBIM has initially been specified by USB-IF for transporting data (IP) between a modem and a host over USB. However some modern modems also support MBIM over PCIe (via MHI). In the same way as QMAP(rmnet), it allows to aggregate IP packets and to perform context multiplexing. This change adds minimal MBIM data transport support to MHI, allowing to support MBIM only modems. MBIM being based on USB NCM, it reuses and copy some helpers/functions from the USB stack (cdc-ncm, cdc-mbim). Note that is a subset of the CDC-MBIM specification, supporting only transport of network data (IP), there is no support for DSS. Moreover the multi-session (for multi-pdn) is not supported in this initial version, but will be added latter, and aligned with the cdc-mbim solution (VLAN tags). This code has been inspired from the mhi_mbim downstream implementation (Carl Yin <carl.yin@quectel.com>). Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: David S.

2021-02-10iwlwifi: mvm: assign SAR table revision to the command laterLuca Coelho
The call to iwl_sar_geo_init() was moved to the end of the iwl_mvm_sar_geo_init() function, after the table revision is assigned to the FW command. But the revision is only known after iwl_sar_geo_init() is called, so we were always assigning zero to it. Fix that by moving the assignment code after the iwl_sar_geo_init() function is called.

2021-02-10iwlwifi: mvm: send stored PPAG command instead of localLuca Coelho
Some change conflicts apparently cause a confusion between a local variable being used to send the PPAG command and the introduction of a union for this command. Most parts of the local command were never copied from the stored data, so the FW was getting garbage in the tables instead of getting valid values. Fix this by completely removing the local and using only the union that we have stored in fwrt.

2021-02-10iwlwifi: mvm: store PPAG enabled/disabled flag properlyLuca Coelho
When reading the PPAG table from ACPI, we should store everything in our fwrt structure, so it can be accessed later. But we had a local ppag_table variable in the function and were erroneously storing the enabled/disabled flag in it instead of storing it in the fwrt. Fix this by removing the local variable and storing everything directly in fwrt.

2021-02-10iwlwifi: mvm: fix the type we use in the PPAG table validity checksLuca Coelho
The value we receive from ACPI is a long long unsigned integer but the values should be treated as signed char. When comparing the received value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison, so the negative value would actually be treated as a very high number. To solve this issue, assign the value to our table of s8's before making the comparison, so the value is already converted when we do so.

2021-02-10iwlwifi: pcie: don't disable interrupts for reg_lockJohannes Berg
The only thing we do touching the device in hard interrupt context is, at most, writing an interrupt ACK register, which isn't racing in with anything protected by the reg_lock. Thus, avoid disabling interrupts here for potentially long periods of time, particularly long periods have been observed with dumping of firmware memory (leading to lockup warnings on some devices.)

2021-02-10iwlwifi: dbg: Mark ucode tlv data as constTakashi Iwai
The ucode TLV data may be read-only and should be treated as const pointers, but currently a few code forcibly cast to the writable pointer unnecessarily. This gave developers a wrong impression as if it can be modified, resulting in crashing regressions already a couple of times. This patch adds the const prefix to those cast pointers, so that such attempt can be caught more easily in future.
