Commit 338de0ca (extcon: gpio: Use gpio driver/chip debounce if supported)
introduced a call to gpio_set_debounce() before actually requesting the
respective gpio pin from the gpio subsystem.
The gpio subsystem expects that a gpio pin was requested before modifying its
state. Not doing so results in a warning from gpiolib, and the gpio pin is
auto-requested. This in turn causes the subsequent devm_gpio_request_one()
to fail. So devm_gpio_request_one() must be called prior to calling
gpio_set_debounce().

Per the AGP 3.0 spec, APBASE is a standard PCI BAR and may be either 32
bits or 64 bits wide. Many drivers read APBASE directly, but they only
handled 32-bit BARs.
The PCI core reads APBASE at enumeration-time. Use pci_bus_address()
instead of reading it again in the driver. This works correctly for both
32-bit and 64-bit BARs.

checksum through skb_checksum_help() if not already done in

Netlink messages. memory mapped netlink i/o is preferred over
zerocopy if it is set up.

Signed-off-by: Gianluca Anzolin <gianluca@sottospazio.it>
Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
This patch fixes two regressions introduced with the recent rfcomm tty
rework.
The current code uses the carrier_raised() method to wait for the
bluetooth connection when a process opens the tty.
However processes may open the port with the O_NONBLOCK flag or set the
CLOCAL termios flag: in these cases the open() syscall returns
immediately without waiting for the bluetooth connection to
complete.
This behaviour confuses userspace which expects an established bluetooth
connection.
The patch restores the old behaviour by waiting for the connection in
rfcomm_dev_activate() and removes carrier_raised() from the tty_port ops.
As a side effect the new code also fixes the case in which the rfcomm
tty device is created with the flag RFCOMM_REUSE_DLC: the old code
didn't call device_move() and ModemManager skipped the detection
probe. Now device_move() is always called inside rfcomm_dev_activate().
