2012-04-20drm/edid: Do drm_dmt_modes_for_range() for all range descriptor typesAdam Jackson
EDID 1.4 retcons the meaning of the "GTF feature" bit to mean "is continuous frequency", and moves the set of supported timing formulas into the range descriptor itself. In any event, the range descriptor can act as a filter on the DMT list without regard to a specific timing formula.

2012-04-20drm/edid: Allow drm_mode_find_dmt to hunt for reduced-blanking modesAdam Jackson
It won't find any, yet. Fix up callers to match: standard mode codes will look prefer r-b modes for a given size if present, EST3 mode codes will look for exactly the r-b-ness mentioned in the mode code. This might mean fewer modes matched for EST3 mode codes between now and when the DMT mode list regrows the r-b modes, but practically speaking EST3 codes don't exist in the wild.

2012-04-20dmaengine: at_hdmac: remove clear-on-read in atc_dostart()Nicolas Ferre
This loop on EBCISR register was designed to clear IRQ sources before enabling a DMA channel. This register is clear-on-read so a race condition can appear if another channel is already active and has just finished its transfer. Removing this read on EBCISR is fixing the issue as there is no case where an IRQ could be pending: we already make sure that this register is drained at probe() time and during resume.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI", switchable using a password protected AT command. Both product ID and USB interface configuration will change when switched. The "sierra_net" driver supports the "Direct IP" mode. This driver supports the "QMI" mode. There are also multiple possible USB interface configurations in each mode, some providing more than one wwan interface. Like many other devices made for Windows, different interface types are identified using a static interface number. We define a Sierra specific interface whitelist to support this.

In the original code "pri == max_num_of_cos" was accepted but it is one past the end of the array. Also we used "pri" before capping it. It's a harmless read past the end of the array, but it would affect which error message gets printed.

2012-04-19xen/xenbus: Add quirk to deal with misconfigured backends.Konrad Rzeszutek Wilk
A rather annoying and common case is when booting a PVonHVM guest and exposing the PV KBD and PV VFB - as broken toolstacks don't always initialize the backends correctly. Normally The HVM guest is using the VGA driver and the emulated keyboard for this (though upstream version of QEMU implements PV KBD, but still uses a VGA driver). We provide a very basic two-stage wait mechanism - where we wait for 30 seconds for all devices, and then for 270 for all them except the two mentioned. That allows us to wait for the essential devices, like network or disk for the full 6 minutes. To trigger this, put this in your guest config: vfb = [ 'vnc=1, vnclisten=0.0.0.0 ,vncunused=1'] instead of this: vnc=1 vnclisten="0.0.0.0" CC: stable@kernel.org Acked-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> [v3: Split delay in non-essential (30 seconds) and essential devices per Ian and Stefano suggestion] [v4: Added comments per Stefano suggestion] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

2012-04-18pch_uart: Fix dma channel unallocated issueTomoya MORINAGA
This driver anticipates pch_uart_verify_port() is not called during installation. However, actually pch_uart_verify_port() is called during installation. As a result, memory access violation occurs like below. 0. initial value: use_dma=0 1. starup() - dma channel is not allocated because use_dma=0 2. pch_uart_verify_port() - Set use_dma=1 3. UART processing acts DMA mode because use_dma=1 - memory access violation occurs! This patch fixes the issue. Solution: Whenever pch_uart_verify_port() is called and then dma channel is not allocated, the channel should be allocated.

2012-04-18USB: ehci-tegra: don't call set_irq_flags(IRQF_VALID)Stephen Warren
This call is not needed; the IRQ controller should (and does) set up interrupts correctly. set_irq_flags() isn't exported to modules, to this also fixes compilation of ehci-tegra.c as a module.
