Currently the module init function registers a platform_device and
only then allocates its IRQ and I/O region. This allows allocation to
race with the device's suspend() function. Instead, allocate
resources in the platform driver's probe() function and free them in
the remove() function.
The module exit function removes the platform device before the
character device that provides access to it. Change it to reverse the
order of initialisation.

Commit ede676c72d ("[...] add digital support for PV SBTVD hybrid")
added "select MEDIA_TUNER_NXP18271" to the VIDEO_CX231XX_DVB Kconfig
entry. But there's no Kconfig symbol MEDIA_TUNER_NXP18271. That should
have been MEDIA_TUNER_TDA18271. (The code added in that commit uses
tda18271_attach, which is only available if MEDIA_TUNER_TDA18271 is
set.)
The selects of MEDIA_TUNER_XC5000 and MEDIA_TUNER_TDA18271 should only
be done if MEDIA_TUNER_CUSTOMISE isn't set.

There's one comment that has been copied from bttv to many other
media/video drivers:
/* init + register i2c algo-bit adapter */
Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.

Smatch complains that the wrong limiter is used here:
drivers/media/dvb/ttpci/av7110.c +906 dvb_feed_start_pid(12)
error: buffer overflow 'npids' 5 <= 19
Here is the problem code:
905 i = dvbdmxfeed->pes_type;
906 npids[i] = (pid[i]&0x8000) ? 0 : pid[i];
"npids" is a 5 element array declared on the stack. If
dvbdmxfeed->pes_type is more than 4 we probably put a (u16)0 past
the end of the array.
If dvbdmxfeed->pes_type is over 4 the rest of the function doesn't
do anything. dvbdmxfeed->pes_type is capped at less than
DMX_TS_PES_OTHER (20) in the caller function, but I changed it to
less than or equal to DMX_TS_PES_PCR (4).

Presently there are a few places that make assumptions about the
existence of SCFCR, which doesn't hold true for several port types. While
generally harmless, this does lead to bogus reads/writes in both the
termios/runtime PM cases that are better off simply never being made in
the first place.
While we're at it, also get rid of a straggling PORT_SCI check that
infers all non-SCI ports contain SCFCR. This doesn't presently have any
impact, but as we're now able to test for the existence of registers
without defering to the port type we future proof for additional port
types.

The UCC UART driver is missing a call to uart_update_timeout().
Without this call, attempting to close the port after outputting large
amounts of data (i.e. using tty and uart buffering) results in long
timeouts before the port will actually be shut down.
For example, cat a large file to a UCC UART port. With the current
driver, the port will stay open for 30 seconds after the last byte
of data is output. But with this patch, the port is closed as
expected, just after the data has been output (tx fifos empty).
