usb: renesas_usbhs: fix the behavior of some usbhs_pkt_handle

Some gadget drivers will call usb_ep_queue() more than once before
the first queue doesn't finish. However, this driver didn't handle
it correctly. So, this patch fixes the behavior of some
usbhs_pkt_handle using the "running" flag. Otherwise, the oops below
happens if we use g_ncm driver and when the "iperf -u -c host -b 200M"
is running.

usb: renesas_usbhs: protect mod->irq_{bemp,brdy}sts by spin lock

This patch protects the mod->irq_bempsts and mod->irq_brdysts by
spin lock in the usbhs_status_get_each_irq() because other functions
will write them during spin lock. Otherwise, the driver will clears
the BRDYSTS and/or BEMPSTS wrongly, and then, the transaction will not
finish.
Also since the driver should use the INTSTS0 and BRDYSTS and BEMPSTS
as the same timing, the patch protects them.

usb: renesas_usbhs: fix the condition of is_done in usbhsf_dma_push_done

This patch fixes the condition of is_done in usbhsf_dma_push_done().
This function will be called after a transmission finished by DMAC.
So, the function should check if the transmission packet is short packet
or not. Also the function should call try_run to send the zero packet
by the pio handler if the "*is_done" is not set. Otherwize, the
transaction will not finish if a gadget driver sets the "zero" flag
in a transmission.

usb: gadget: f_fs: fix the redundant ep files problem

Up to now, when endpoint addresses in descriptors were non-consecutive,
there were created redundant files, which could cause problems in kernel,
when user tried to read/write to them. It was result of fact that maximum
endpoint address was taken as total number of endpoints in function.

This patch adds endpoint descriptors counting and storing their addresses
in eps_addrmap to verify their cohesion in each speed.

Endpoint address map would be also useful for further features, just like
vitual endpoint address mapping.

usb: phy: tegra: Avoid use of sizeof(void)

The PHY configuration is stored in an opaque "config" field, but when
allocating the structure, its proper size needs to be known. In the case
of UTMI, the proper structure is tegra_utmip_config of which a local
variable already exists, so we can use that to obtain the size from.

Fixes the following warning from the sparse checker:

	drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void)

ASoC: tlv320aic31xx: Fix 24bit samples with I2S format and 12MHz mclk

I2S format requires bitclock to have an exact amount of cycles in a
frame for audio to work cleanly. With dsp formats that is not so
important.

Updates aic31xx_setup_pll() to look for a line in aic31xx_divs table
that produces the best match for the bitclock and adds lines to
aic31xx_divs for 12MHz mclk and 24bit samples.

netfilter: nfnetlink: deliver netlink errors on batch completion

We have to wait until the full batch has been processed to deliver the
netlink error messages to userspace. Otherwise, we may deliver
duplicated errors to userspace in case that we need to abort and replay
the transaction if any of the required modules needs to be autoloaded.

A simple way to reproduce this (assumming nft_meta is not loaded) with
the following test file:

 add table filter
 add chain filter test
 add chain bad test                 # intentional wrong unexistent table
 add rule filter test meta mark 0

Then, when trying to load the batch:

 # nft -f test
 test:4:1-19: Error: Could not process rule: No such file or directory
 add chain bad test
 ^^^^^^^^^^^^^^^^^^^
 test:4:1-19: Error: Could not process rule: No such file or directory
 add chain bad test
 ^^^^^^^^^^^^^^^^^^^

The error is reported twice, once when the batch is aborted due to
missing nft_meta and another when it is fully processed.

blk-mq: cleanup after blk_mq_init_rq_map failures

In blk-mq.c blk_mq_alloc_tag_set, if:
	set->tags = kmalloc_node()
succeeds, but one of the blk_mq_init_rq_map() calls fails,
	goto out_unwind;
needs to free set->tags so the caller is not obligated
to do so.  None of the current callers (null_blk,
virtio_blk, virtio_blk, or the forthcoming scsi-mq)
do so.

set->tags needs to be set to NULL after doing so,
so other tag cleanup logic doesn't try to free
a stale pointer later.  Also set it to NULL
in blk_mq_free_tag_set.

Tested with error injection on the forthcoming
scsi-mq + hpsa combination.
