This file is big. It has 12000+ lines! Most of the defined stuff aren't
used anyware inside the driver, so we can just remove most of the lines
and still keep everything that have any interest for the driver.

If anyone ever need the other devices, it will be stored at git logs, so
it is easy to recover.

The diff result is impressive:
 1 files changed, 1013 insertions(+), 12694 deletions(-)
 rewrite drivers/media/dvb/frontends/drxd_map_firm.h (90%)

As a sideback effect, drxd driver will likely compile faster, and
checkpatch.pl can run on this file without taking (literally) hours.

The code cleanup was done using this small script:
	$ for i in `perl -ne 'print "$1\n" if (m/define\s+([^\s+]+)/)' drxd_map_firm.h`; do if [ "`grep $i drivers/media/dvb/frontends/drxd*.[ch]`" != "" ] ; then echo $i; fi; done|sort|uniq >used_symbols
	$ grep -f used_symbols drxd_map_firm.h >defines

And then deleting the old #define lines, replacing by "defines" file content.

The em28xx bridge strobes the reset pin on the drx-d on every ts_ctrl call.
This results in the state of the chip getting out of the sync with the
state of the driver (and hence all tuning requests after the first one fail).

Make sure the drx-d is not being held in reset, but don't actually perform a
hardware reset on the chip.

The GPIO block has been split out from the other HVR-9x0 variants to reduce
the risk of regression, although in theory they would not have any issues
since none of those cases have the frontend driver managing any internal
state.

If the tuner is not actually behind an i2c gate, using the i2c gate control
function can wedge the i2c bus.  Provide the ability to control on a per-board
basis whether it should be used.

Problem was noticed on the HVR-900 R2, where it resulted in the first tuning
attempt succeeding, and then all subsequent attempts to access the xc3028

Brazil uses 6MHz-spaced channels. So, the nyquist filter for
DVB-C should be different, otherwise, inter-channel interference
may badly affect the device, and signal may not be properly decoded.

On my tests here, without this patch, sometimes channels are seen,
but, most of the time, PID filter returns with timeout.

  MIPS: RB532: Fix iomap resource size miscalculation.

Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

If two drivers are probing devices at the same time, both will write
their match table result to the dev->of_match cache at the same time.

Only write the result if the device matches.

In a thread titled "SBus devices sometimes detected, sometimes not",
Meelis reported his SBus hme was not detected about 50% of the time.
From the debug suggested by Grant it was obvious another driver matched
some devices between the call to match the hme and the hme discovery
failling.

configfs_readdir() will use the existing inode numbers of inodes in the
dcache, but it makes them up for attribute files that aren't currently
instantiated.  There is a race where a closing attribute file can be
tearing down at the same time as configfs_readdir() is trying to get its
inode number.

We want to get the inode number of open attribute files, because they
should match while instantiated.  We can't lock down the transition
where dentry->d_inode is set to NULL, so we just check for NULL there.
We can, however, ensure that an inode we find isn't iput() in
configfs_d_iput() until after we've accessed it.

When configfs is faking mkdir() on its subsystem or default group
objects, it starts by adding a negative dentry.  It then tries to
instantiate the group.  If that should fail, it must clean up after
itself.

I was using d_delete() here, but configfs_attach_group() promises to
return an empty dentry on error.  d_delete() explodes with the entry
dentry.  Let's try d_drop() instead.  The unhashing is what we want for
our dentry.

Let's check a scenario:
1. blk_delay_queue(q, SCSI_QUEUE_DELAY);
2. blk_run_queue_async();
the second one will became a noop, because q->delay_work already has
WORK_STRUCT_PENDING_BIT set, so the delayed work will still run after
SCSI_QUEUE_DELAY. But blk_run_queue_async actually hopes the delayed
work runs immediately.

Fix this by doing a cancel on potentially pending delayed work
before queuing an immediate run of the workqueue.
