[ Upstream commit f65607cdbc ]
When we set up a TDLS station, we set sta->sta.bandwidth solely based
on the capabilities, because the "what's the current bandwidth" check
is bypassed and only applied for other types of stations.
This leads to the unfortunate scenario that the sta->sta.bandwidth is
160 MHz if both stations support it, but we never actually configure
this bandwidth unless the AP is already using 160 MHz; even for wider
bandwidth support we only go up to 80 MHz (at least right now.)
For iwlwifi, this can also lead to firmware asserts, telling us that
we've configured the TX rates for a higher bandwidth than is actually
available due to the PHY configuration.
For non-TDLS, we check against the interface's requested bandwidth,
but we explicitly skip this check for TDLS to cope with the wider BW
case. Change this to
(a) still limit to the TDLS peer's own chandef, which gets factored
into the overall PHY configuration we request from the driver,
and
(b) limit it to when the TDLS peer is authorized, because it's only
factored into the channel context in this case.

If generic_drop_inode() returns true, it means iput_final() can evict
this inode regardless of whether it is dirty or not. If we check
I_DONTCACHE in generic_drop_inode(), any inode with this bit set will be
evicted unconditionally. This is not the desired behavior because
I_DONTCACHE only means the inode shouldn't be cached on the LRU list.
As for whether we need to evict this inode, this is what
generic_drop_inode() should do. This patch corrects the usage of
I_DONTCACHE.
This patch was proposed in [1].

pm_runtime_get_sync() will increment pm usage at first and it

error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, it will result in reference leak in
the two functions(gpmi_init and gpmi_nfc_exec_op). Moreover,
this device cannot enter the idle state and always stay busy or

pm_runtime_put_noidle.

I would repeat the same commit message that was in commit 5e4b7e82d4
("clk: qcom: gcc-sdm845: Use floor ops for sdcc clks") but it seems
silly to do so when you could just go read that commit.
NOTE: this is actually extra terrible because we're missing the 50 MHz
rate in the table (see the next patch AKA ("clk: qcom: gcc-sc7180: Add
50 MHz clock rate for SDC2")). That means then when you run an older
SD card it'll try to clock it at 100 MHz when it's only specced to run
at 50 MHz max. As you can probably guess that doesn't work super

SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core

Since commit b4868b44c5 ("NFSv4: Wait for stateid updates after
CLOSE/OPEN_DOWNGRADE"), every inter server copy operation suffers 5
seconds delay regardless of the size of the copy. The delay is from
nfs_set_open_stateid_locked when the check by nfs_stateid_is_sequential
fails because the seqid in both nfs4_state and nfs4_stateid are 0.
Fix by modifying nfs4_init_cp_state to return the stateid with seqid 1
instead of 0. This is also to conform with section 4.8 of RFC 7862.
Here is the relevant paragraph from section 4.8 of RFC 7862:
A copy offload stateid's seqid MUST NOT be zero. In the context of a
copy offload operation, it is inappropriate to indicate "the most
recent copy offload operation" using a stateid with a seqid of zero
(see Section 8.2.2 of [RFC5661]). It is inappropriate because the
stateid refers to internal state in the server and there may be
several asynchronous COPY operations being performed in parallel on
the same file by the server. Therefore, a copy offload stateid with
a seqid of zero MUST be considered invalid.
