sched/headers: Prepare to remove inclusion from

2017-03-02T07:42:31+00:00

Add #include dependencies to all .c files rely on sched.h doing that for them. Note that even if the count where we need to add extra headers seems high, it's still a net win, because is included in over 2,200 files ...

Pull i2c updates from Wolfram Sang: "I2C has for you two new drivers (Tegra BPMP and STM32F4), interrupt support for pca954x muxes, and a bunch of driver bugfixes and improvements. Nothing really special this cycle. A few commits have been added to my tree just recently. Those are the Tegra BPMP driver and a few straightforward bugfixes or cleanups which I prefer to have upstream rather soonish. The rest had proper linux-next exposure" * 'i2c/for-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (25 commits) i2c: thunderx: Replace pci_enable_msix() i2c: exynos5: fix arbitration lost handling i2c: exynos5: disable fifo-almost-empty irq signal when necessary i2c: at91: ensure state is restored after suspending i2c: bcm2835: Avoid possible NULL ptr dereference i2c: Add Tegra BPMP I2C proxy driver dt-bindings: Add Tegra186 BPMP I2C binding misc: eeprom: at24: use device_property_*() functions instead of of_get_property() i2c: mux: pca954x: Add interrupt controller support dt: bindings: i2c-mux-pca954x: Add documentation for interrupt controller i2c: mux: pca954x: Add missing pca9542 definition to chip_desc i2c: riic: correctly finish transfers i2c: i801: Add support for Intel Gemini Lake i2c: mux: pca9541: Export OF device ID table as module aliases i2c: mux: pca954x: Export OF device ID table as module aliases i2c: mux: mlxcpld: remove unused including i2c: busses: constify i2c_algorithm structures i2c: i2c-mux-gpio: rename i2c-gpio-mux to i2c-mux-gpio i2c: sh_mobile: document support for r8a7796 (R-Car M3-W) i2c: i2c-cros-ec-tunnel: Reduce logging noise ...

misc: eeprom: at24: use device_property_*() functions instead of of_get_property()

2017-02-11T20:23:43+00:00

Allow the at24 driver to get configuration information from both OF and ACPI by using the more generic device_property functions. This change was inspired by the at25.c driver. I have a custom board with a ST M24C02 EEPROM attached to an I2C bus. With the following ACPI construct, this patch instantiates a working instance of the driver. Device (EEP0) { Name (_HID, "PRP0001") Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package () {"compatible", Package () {"st,24c02"}}, Package () {"pagesize", 16}, }, }) Name (_CRS, ResourceTemplate () { I2cSerialBus ( 0x0057, ControllerInitiated, 400000, AddressingMode7Bit, "\\_SB.PCI0.I2C3", 0x00, ResourceConsumer,,) }) } Signed-off-by: Ben Gardner Reviewed-by: Andy Shevchenko Signed-off-by: Wolfram Sang

eeprom: idt_89hpesx: Drop kfree for memory allocated with devm_kzalloc

2017-01-27T08:13:57+00:00

It's not necessary to free memory allocated with devm_kzalloc and using kfree leads to a double free. Fixes: cfad6425382e ("eeprom: Add IDT 89HPESx EEPROM/CSR driver") Signed-off-by: Wei Yongjun Signed-off-by: Dan Carpenter Acked-by: Serge Semin Signed-off-by: Greg Kroah-Hartman

eeprom: idt_89hpesx: Discard memory freeing allocated by devm_kmalloc

2017-01-27T08:13:57+00:00

Indeed, the data structure is allocated by device resource manager, so the driver doesn't need to free anything on remove() callback. Reported-by: Julia Lawall Signed-off-by: Serge Semin Signed-off-by: Greg Kroah-Hartman

eeprom: fix memory leak on buf when failed allocation of csraddr_str

2017-01-25T10:41:44+00:00

The error return path When csraddr_str fails to free buf, causing a memory leak. Fix this by returning via the free_buf label that performs the necessary cleanup. Signed-off-by: Colin Ian King Signed-off-by: Greg Kroah-Hartman

eeprom: Add IDT 89HPESx EEPROM/CSR driver

2017-01-19T10:39:57+00:00

This driver provides an access to EEPROM of IDT PCIe-switches. IDT PCIe- switches expose a simple SMBus interface to perform IO-operations from/to EEPROM, which is located at private (so called Master) SMBus. The driver creates a simple binary sysfs-file to have an access to the EEPROM using the SMBus-slave interface in the i2c-device susfs-directory: /sys/bus/i2c/devices/-/eeprom In case if read-only flag is specified at dts-node of the device, User-space applications won't be able to write to the EEPROM sysfs-node. Additionally IDT 89HPESx SMBus interface has an ability to read/write values of device CSRs. This driver exposes debugfs-file to perform simple IO-operations using that ability for just basic debug purpose. Particularly the next file is created in the specific debugfs-directory: /sys/kernel/debug/idt_csr/ Format of the debugfs-file value is: $ cat /sys/kernel/debug/idt_csr/-/; : So reading the content of the file gives current CSR address and it value. If User-space application wishes to change current CSR address, it can just write a proper value to the sysfs-file: $ echo "" > /sys/kernel/debug/idt_csr/-/ If it wants to change the CSR value as well, the format of the write operation is: $ echo ":" > \ /sys/kernel/debug/idt_csr/-/; CSR address and value can be any of hexadecimal, decimal or octal format.
