This patch fixes an issue introduced by commit ID 6a81c26f [net/stmmac: remove conditional compilation of clk code], which switched from the internal stmmac_clk_{en}{dis}able calls to clk_{en}{dis}able. By this, calling clk_prepare and clk_unprepare was removed. clk_{un}prepare is mandatory for platforms using common clock framework. Since these drivers are used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for them. Otherwise the clocks are not correctly en-/disabled and ethernet support doesn't work.

In case of error, the function clk_get() returns ERR_PTR() and never returns NULL pointer. The NULL test in the error handling should be replaced with IS_ERR(). dpatch engine is used to auto generated this patch.

This patch fixes a build failure introduced in commit 66636287 ("gianfar: Support the get_ts_info ethtool method.").

Since version 7.4 the FW configures in the pci config space the max number of interrupts available to the physical function, instead of the exact number to use. This causes a false warning in driver when comparing the number of configured interrupts to the number about to be used.

The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use the same subclass to identify the QMI/wwan function. Replace the existing device specific UML290 entries with generic vendor matching, adding support for the Pantech P4200. The ZTE MF683 has 6 vendor specific interfaces, all using ff/ff/ff for cls/sub/prot. Adding a match on interface #5 which is a QMI/wwan interface.

Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance regression for IPv6. Rx checksum offload does not work. IPv6 packets are passed to the stack with CHECKSUM_NONE.

This patch adds on the fixes done in commits 89dd86db ("mlx4_core: Allow large mlx4_buddy bitmaps") and 3de819e6 ("mlx4_core: Fix integer overflow issues around MTT table") so that memory registration of up to 8TB (log_num_mtt=31) finally works. It fixes integer overflows in a few mlx4_table_yyy routines in icm.c by using a u64 intermediate variable, and int/uint issues that caused table indexes to become nagive by setting some variables to be u32 instead of int. These problems cause crashes when a user attempted to register > 512GB of RAM.

This fixes a hang on suspend due to calling wdm_suspend on the unregistered data interface. The hang should have been a NULL pointer reference had it not been for a logic error in the cdc_wdm code. commit 230718bd net: qmi_wwan: bind to both control and data interface changed qmi_wwan to use cdc_wdm as a subdriver for devices with a two-interface QMI/wwan function. The commit failed to update qmi_wwan_suspend and qmi_wwan_resume, which were written to handle either a single combined interface function, or no subdriver at all. The result was that we called into the subdriver both when the control interface was suspended and when the data interface was suspended. Calling the subdriver suspend function with an unregistered interface is not supported and will make the subdriver bug out. Signed-off-by: NBjørn Mork <bjorn@mork.no> Signed-off-by: NDavid S.

To allow for usage of the flow steering Firmware structures in more locations over the driver, such as the resource tracker, move them from mcg.c to common header files.

This patch fixes a bug found by Nish Aravamudan (https://lkml.org/lkml/2012/5/15/220) where the driver is not following the spec (it is not aligning the rx buffer on a 16-byte boundary) and the hypervisor aborts the registration, making the device unusable. The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461) to replace the kmalloc+map for a single call to dma_alloc_coherent() because that function always aligns to a 16-byte boundary. The stable trees will run into this bug whenever the rx buffer kmalloc call returns something not aligned on a 16-byte boundary.

When the interface is down, the hardware is powered off. However, the suspend handler currently tries to send host sleep commands (when wakeup params are set) in this configuration, causing a system hang when going into suspend (the commands will never complete). Avoid this by detecting this situation and simply returning from the suspend handler without doing anything special.

On our system (ARM Cortex-M3 SOC running linux-2.6.33) frequent crashes were observed in the rt2800usb module because of the invalid length of the received packet (3392, 46920...). This patch adds the sanity check on the packet legth. Also, changed WARNING to ERROR in rt2x00lib_rxdone() so that the bad packet condition would be noticed. The fix was tested on the latest compat-wireless-3.5.1-1-snpc.
