Daniel Golle d4c999bb89 mac80211: rt2x00: backport accepted and pending patches from upstream
backport from wireless-drivers-next, replacing some existing patches in
our tree (marked with '=' are those which were already present):
 f483039cf51a rt2x00: use simple_read_from_buffer()
=5c656c71b1bf rt2800: move usb specific txdone/txstatus routines to rt2800lib
=0b0d556e0ebb rt2800mmio: use txdone/txstatus routines from lib
=5022efb50f62 rt2x00: do not check for txstatus timeout every time on tasklet
=adf26a356f13 rt2x00: use different txstatus timeouts when flushing
=0240564430c0 rt2800: flush and txstatus rework for rt2800mmio
 6eba8fd22352 rt2x00: rt2400pci: mark expected switch fall-through
 10bb92217747 rt2x00: rt2500pci: mark expected switch fall-through
 916e6bbcfcff rt2x00: rt2800lib: mark expected switch fall-throughs
 641dd8068ecb rt2x00: rt61pci: mark expected switch fall-through
 750afb08ca71 cross-tree: phase out dma_zalloc_coherent()
=c2e28ef7711f rt2x00: reduce tx power to nominal level on RT6352
 a4296994eb80 rt2x00: Work around a firmware bug with shared keys
 2587791d5758 rt2x00: no need to check return value of debugfs_create functions

pending on linux-wireless:
 rt2x00: remove unneeded check
 rt2x00: remove confusing AGC register
 rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band
 rt2800: enable TX_PIN_CFG_RFRX_EN only for MT7620
 rt2800: comment and simplify AGC init for RT6352
 rt2x00: do not print error when queue is full
 rt2800: partially restore old mmio txstatus behaviour
 rt2800: new flush implementation for SoC devices
 rt2800: move txstatus pending routine
 rt2800mmio: fetch tx status changes
 rt2800mmio: use timer and work for handling tx statuses timeouts
 rt2x00: remove last_nostatus_check
 rt2x00: remove not used entry field
 rt2x00mmio: remove legacy comment

While at it also rename some existing patches now that there are
separate folders with patches for each driver to make things a bit
nicer to handle.
