bd336e6344 [media] dvb: make DVB frontend *_ops instances "const"
These are immutable.  Making them "const" allows the compiler to move
them to the "rodata" section.

Note that cxd2841er_t_c_ops cannot be made "const", because
cxd2841er_attach() modifies it.  Ouch!

7e3e68bcfd [media] dvb_frontend: pass the props cache to get_frontend() as arg
Instead of using the DTV properties cache directly, pass the get
frontend data as an argument. For now, everything should remain
the same, but the next patch will prevent get_frontend to
affect the global cache.

This is needed because several drivers don't care enough to only
change the properties if locked. Due to that, calling
G_PROPERTY before locking on those drivers will make them to
never lock. Ok, those drivers are crap and should never be
merged like that, but the core should not rely that the drivers
would be doing the right thing.

0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

27f7ef7ca9 [media] lgdt3305: add support for fixed tp clock mode
Add support for controlling TP clock mode for VSB and QAM annex-B/C mode.
Gated clock mode is the default value, and does not support QAM annex-C.
The patch enables setting this control to fixed clock mode.

Simplify the code a little bit by removing some uneeded arguments

215cedec37 [media] media: remove emacs editor variables
1) This is not allowed by the kernel coding style
2) Just configure your editor correctly
3) It's really ugly

c9af5c1542 [media] lgdt3305: include sleep functionality in lgdt3304_ops
Add sleep ops to lgdt3304_ops to invoke lgdt3305_sleep() to be called
from dvb_frontend_suspend(). lgdt3305_soft_reset() is called for both
3304 and 3305 devices. soft_reset and sleep touch LGDT3305_GEN_CTRL_3
on 3304 and 3305 devices. Hence, adding sleep to lgdt3304_ops will help
suspend 3304 properly from dvb_frontend_suspend().
