Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space times out.
The original fix for b43legacy (commit a3ea2c7) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43legacy is built as a module;
however, it fails when the driver is compiled into the kernel.
This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. The remaining
firmware files are read synchronously.

This adds support for bcma wifi core revision 17 which is found on
BCM4716/4717/4718 SoCs. The firmware version 610.812 for brcmsmac found
in linux-firmware does not support these cores, but a firmware
generated with b43-fwcutter from the proprietary broadcom wireless
driver works with these chips. This wifi core contains a revision 5
N-PHY and a revision 7 radio of type 0x2056.

This reverts commit f74b9d365ddd33a375802b064f96a5d0e99af7c0.
Turns out reverting commit a240dc7b3c7463bd60cf0a9b2a90f52f78aae0fd
"ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to
bring the tx power back to normal levels on devices like the
Buffalo WZR-HP-G450H, this one needs to be reverted as well.
This revert improves tx power by ~10 db on that device

mmc: sdhci-acpi: enable runtime-pm for device HID INT33C6
|
|
sdhci-acpi supports ACPI devices which have compatibility ID
PNP0D40, however it is not possible to know if those devices
will all work correctly with runtime-pm, so that must be configured
per hardware ID.
For INT33C6, several related quirks, capabilities and flags are set:
MMC_CAP_NONREMOVABLE
The SDIO card will never be removable
SDHCI_ACPI_RUNTIME_PM
Enable runtime-pm of the host controller
MMC_CAP_POWER_OFF_CARD
Enable runtime-pm of the SDIO card
MMC_PM_KEEP_POWER
SDIO card has the capability to remain powered up
during system suspend
SDHCI_QUIRK2_HOST_OFF_CARD_ON
Always do a full reset during system resume
because the card may be already initialized having
not been powered off.
Wake-ups from the INT33C6 host controller are not supported, so the
following capability must *not* be set:
MMC_PM_WAKE_SDIO_IRQ
Enable wake on card interrupt

is from per ifconfig up to once when the device is connected.

on ifconfig down/up. Also devices that have no EEPROM are
assigned a new random address on ifconfig down/up instead of
persisting the same one.

In case we rename a directory, ext4_rename has to read the dir block
and change its dotdot's information. The old ext4_rename encapsulated
the dir_block read into itself. So this patch adds a new function
ext4_get_first_dir_block() which gets the dir buffer information so
the ext4_rename can handle it properly. As it will also change the
parent inode number, we return the parent_de so that ext4_rename() can
handle it more easily.
ext4_find_entry is also changed so that the caller(rename) can tell
whether the found entry is an inlined one or not and journaling the
corresponding buffer head.

This patch let add_dir_entry handle the inline data case. So the
dir is initialized as inline dir first and then we can try to add
some files to it, when the inline space can't hold all the entries,
a dir block will be created and the dir entry will be moved to it.
Also for an inlined dir, "." and ".." are removed and we only use
4 bytes to store the parent inode number. These 2 entries will be
added when we convert an inline dir to a block-based one.
