Subject: [Patch v2 00/13] Introduce ACPI _DSM helper functions to simplify code
Date: Thu, 19 Dec 2013 20:38:09 +0800 [thread overview]
Message-ID: <1387456702-4709-1-git-send-email-jiang.liu@linux.intel.com> (raw)
There are several drivers making use of ACPI _DSM method to detect
and invoke device specific methods. Currently every driver has
implemented its private version to support ACPI _DSM method.
So this patch introduces three helper functions to support ACPI _DSM
method, which will be used to replace open-coded versions. It helps
to simplify code and improve code readability.
It also includes some bugfixes for TPM/nouveau drivers.
It applies to the mainstream kernel on top of
b0031f2 Merge tag 's2mps11-build' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Due to lacking of hardware platform, I have only tested the ACPI _DSM
helper functions and TPM related changes, but haven't tested changes to
other drivers yet. So appreciate help to review and test these patches.
V1->V2
1) fix an issue in initializing acpi_object structure
Jiang Liu (13):
ACPI: introduce helper interfaces to support ACPI _DSM method
ACPI, extlog: replace open-coded _DSM specific code with helper
functions
PCI, pci-label: release allocated ACPI object on error recovery path
ACPI, PCI: replace open-coded _DSM specific code with helper
functions
PCI, pci-label: treat PCI label with index 0 as valid label
ACPI, TPM: fix memory leak when walking ACPI namespace
ACPI, TPM: matching node name instead of full path when searching for
TPM device
ACPI, TPM: replace open-coded _DSM specific code with helper
functions
ACPI, TPM: detecting PPI features by checking availability of _DSM
functions
ACPI, i2c-hid: replace open-coded _DSM specific code with helper
functions
ACPI, i915: replace open-coded _DSM specific code with helper
functions
nouveau: fix memory leak in ACPI _DSM related code
ACPI, nouveau: replace open-coded _DSM specific code with helper
functions
