[ Upstream commit 6549c46af8551b346bcc0b9043f93848319acd5c ]

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.

[ Upstream commit 9cf76a72af6ab81030dea6481b1d7bdd814fbdaf ]

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.

-#define AIC31XX_BCLK_MASTER		0x08
-#define AIC31XX_WCLK_MASTER		0x04
+#define AIC31XX_BCLK_MASTER		BIT(2)
+#define AIC31XX_WCLK_MASTER		BIT(3)

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

[ Upstream commit 9c23aa51477a37f8b56c3c40192248db0663c196 ]

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.

From: Eric Woudstra <ericwouds@gmail.com>

[ 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.

In some cases skb head could be locked and entire header
data is pulled from skb. When skb_zerocopy() called in such cases,
following BUG is triggered. This patch fixes it by copying entire
skb in such cases.
This could be optimized incase this is performance bottleneck.

A few days after this patch, I send in another as it needs a fix. If you apply this patch, please also apply the other: set ivl bit only for vid larger than 1.
