For linear regulators, the n_voltages should be (max - min) / step + 1.
Buck voltage from 1v to 3V, per step 100mV, and vout mask is 0x1f. If value is from 20 to 31, the voltage will all be fixed to 3V. And LDO also, just vout range is different from 1.2v to 3v, step is the same. If value is from 18 to 31, the voltage will also be fixed to 3v.

In case of Full-Duplex mode, DXP flag is set when RXP and TXP flags are set. But to avoid 2 different handlings, just add TXP and RXP flag in the mask instead of DXP, and then keep the initial handling of TXP and RXP events. Also rephrase comment about EOTIE which is one of the interrupt enable bits. It is not triggered by any event.

These are backwards from Table 7-71 of the TLV320AIC3100 spec [1].
This was broken in 12eb4d66ba2e when BCLK_MASTER and WCLK_MASTER were converted from 0x08 and 0x04 to BIT(2) and BIT(3), respectively.

Probably just a typo since the defines were not listed in bit order.

rtl8152_close() takes the refcount via usb_autopm_get_interface() but it doesn't release when RTL8152_UNPLUG test hits. This may lead to the imbalance of PM refcount. This patch addresses it.

In this case, qed_hw_prepare() returns error due to hw/fw error, but in theory work queue should be in process context instead of interrupt.
The root cause might be the unpaired spin_{un}lock_bh() in _qed_mcp_cmd_and_union(), which causes botton half is disabled incorrectly.

[ Upstream commit 11d8d98cbeef1496469b268d79938b05524731e8 ]
According to reference guides mt7530 (mt7620) and mt7531:
NOTE: When IVL is reset, MAC[47:0] and FID[2:0] will be used to read/write the address table. When IVL is set, MAC[47:0] and CVID[11:0] will be used to read/write the address table.
Since the function only fills in CVID and no FID, we need to set the IVL bit. The existing code does not set it.
This is a fix for the issue I dropped here earlier:
http://lists.infradead.org/pipermail/linux-mediatek/2021-June/025697.html
With this patch, it is now possible to delete the 'self' fdb entry manually. However, wifi roaming still has the same issue, the entry does not get deleted automatically. Wifi roaming also needs a fix somewhere else to function correctly in combination with vlan.

Commit 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer that was possibly NULL. That fails miserably, because that helper inline function is not set up to handle that case.
Just make acpi_dev_put() silently accept a NULL pointer, rather than calling down to put_device() with an invalid offset off that NULL pointer.
