Subject: Applied "spi: Respect DataBitLength field of SpiSerialBusV2() ACPI resource" to the spi tree
Date: Tue, 14 Apr 2020 12:40:02 +0100 [thread overview]
Message-ID: <applied-20200413180406.1826-1-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200413180406.1826-1-andriy.shevchenko@linux.intel.com>
The patch
spi: Respect DataBitLength field of SpiSerialBusV2() ACPI resource
has been applied to the spi tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

Subject: [PATCH] spi: Respect DataBitLength field of SpiSerialBusV2() ACPI
resource
By unknown reason the commit 64bee4d28c9e
("spi / ACPI: add ACPI enumeration support")
missed the DataBitLength property to encounter when parse SPI slave
device data from ACPI.
Fill the gap here.
Fixes: 64bee4d28c9e ("spi / ACPI: add ACPI enumeration support")
