Custom function for 'map_irq' was introduced in
commit fab6710e4c51 ("staging: mt7621-pci: fix PCIe interrupt mapping")

After some testing in an adquired device with a similar
pci layout that those that was having problems, I got
into a better way to solve the issue just using device tree
'interrupt-map' and 'interrupt-map-mask' properties. For
this to be possible we must avoid custom configuration of
the virtual bridges registers from driver code. Doing in
this way buses are not reconfigured so we can properly

correctly the interrupts. Hence remove custom configuration
of the bridges as well as custom 'map_irq' related stuff.

staging: fbtft: Don't spam logs when probe is deferred

When requesting GPIO line the probe can be deferred.
In such case don't spam logs with an error message.
This can be achieved by switching to dev_err_probe().

staging: fbtft: Rectify GPIO handling

The infamous commit c440eee1a7a1 ("Staging: staging: fbtft: Switch to
the GPIO descriptor interface") broke GPIO handling completely.
It has already four commits to rectify and it seems not enough.
In order to fix the mess here we:

  1) Set default to "inactive" for all requested pins

  2) Fix CS#, RD#, and WR# pins polarity since it's active low
     and GPIO descriptor interface takes it into consideration
     from the Device Tree or ACPI

  3) Consolidate chip activation (CS# assertion) under default
     ->reset() callback

To summarize the expectations about polarity for GPIOs:

   RD# Low
   WR# Low
   CS# Low
   RESET# Low
   DC or RS High
   RW High
   Data 0 .. 15 High

See also Adafruit learning course [1] for the example of the schematics.

While at it, drop unneeded NULL checks, since GPIO API is tolerant to that.

staging: rtl8188eu: remove enum WIFI_FRAME_SUBTYPE

The values defined in enum WIFI_FRAME_SUBTYPE are the same the #define
IEEE80211_STYPE_xxx from <linux/ieee80211.h>.

Special care must be taken for control and data frame, because  the coding
of the frame type is not included in the IEEE80211_STYPE_xxx values and
must be added explicitly.

There is no problem for management frame because the type si coded as (0)
(in rtl8188eu) and (0x0000) (in <linux/ieee80211.h>).

Values used for control frame (WIFI_PSPOLL) must be OR'eded with
IEEE80211_FTYPE_CTL.

Values used for data frame (WIFI_DATA_NULL and WIFI_QOS_DATA_NULL) must be
OR'ed with IEEE80211_FTYPE_DATA.

Use theses values to avoid code duplication.

staging: rtl8712: Fix some tests against some 'data' subtype frames

Commit 6e2baa44c6d1 ("staging: rtl8712: remove enum WIFI_FRAME_SUBTYPE")
was wrong because:
WIFI_DATA_NULL != IEEE80211_STYPE_NULLFUNC
WIFI_DATA_CFACK != IEEE80211_STYPE_DATA_CFACK
WIFI_DATA_CFPOLL != IEEE80211_STYPE_DATA_CFPOLL
WIFI_DATA_CFACKPOLL != IEEE80211_STYPE_DATA_CFACKPOLL

the WIFI_DATA_xxx definitions include WIFI_DATA_TYPE, which is 'BIT(3)'.
Restore the previous behavior by adding the missing
'IEEE80211_FTYPE_DATA |' (0x0008, that is to say BIT(3)) when these values
are used.

Hopefully, the wrong commit was small enough and hand review is possible.
