2014-10-01r8169:change the name of function"rtl_w1w0_eri"Chun-Hao Lin
Change the name of function "rtl_w1w0_eri" to "rtl_w0w1_eri". In this function, the local variable "val" is "write zeros then write ones". Please see below code. (val & ~m) | p In this patch, change the function name from "xx_w1w0_xx" to "xx_w0w1_xx". The changed function name is more suitable for it's behavior.

2014-10-01r8169:for function "rtl_w1w0_phy" change its name and behaviorChun-Hao Lin
Change function name from "rtl_w1w0_phy" to "rtl_w0w1_phy". And its behavior from "write ones then write zeros" to "write zeros then write ones". In Realtek internal driver, bitwise operations are almost "write zeros then write ones". For easy to port hardware parameters from Realtek internal driver to Linux kernal driver "r8169", we would like to change this function's behavior and its name.

2014-10-01HID: uHID: fix excepted report typeBenjamin Tissoires
When uhid_get_report() or uhid_set_report() are called, they emit on the char device a UHID_GET_REPORT or UHID_SET_REPORT message. Then, the protocol says that the user space asnwers with UHID_GET_REPORT_REPLY or UHID_SET_REPORT_REPLY. Unfortunatelly, the current code waits for an event of type UHID_GET_REPORT or UHID_SET_REPORT instead of the reply one. Add 1 to UHID_GET_REPORT or UHID_SET_REPORT to actually wait for the reply, and validate the reply.

2014-10-01spi: orion: support armada extended baud ratesGreg Ungerer
The Armada SoC family implementation of this SPI hardware module has extended the configuration register to allow for a wider range of SPI clock rates. Specifically the Serial Baud Rate Pre-selection bits in the SPI Interface Configuration Register now also use bits 6 and 7 as well. Modify the baud rate calculation to handle these differences for the Armada case. Potentially a baud rate can be setup using a number of different pre-scalar and scalar combinations. This code tries all possible pre-scalar divisors (8 in total) to try and find the most accurate set. This change introduces (and documents) a new device tree compatible device name "armada-370-spi" to support this.

2014-10-01PCI/MSI: Add "msi_bus" sysfs MSI/MSI-X control for endpointsYijing Wang

Add "msi_bus" support for endpoints, so an administrator can prevent the use of MSI and MSI-X for individual devices. Note that as for bridges, these changes only affect future driver requests for MSI or MSI-X, so drivers may need to be reloaded. Add documentation for the "msi_bus" sysfs file.

2014-10-01of: Fix NULL dereference in selftest removal codeGrant Likely
The selftest code removes its testcase data from the live tree when exiting, but if the testcases data tree contains an empty child of the root, then it causes an oops due to a NULL dereference. The reason is that the code tries to directly dereference the child pointer without checking first if a child is actually there. The solution is to pass the parent node into detach_node_and_children() instead of trying to pass the child. This required removing the code that attempts to remove all of the sibling nodes in detach_node_and_children(), which was never sensible in the first place. At the same time add a check to make sure the bounds of the nodes list are not exceeded by the testdata tree. If they are then abort.
