The commit d3cb25a12138 ("usb: gadget: udc: fix spin_lock in pch_udc")
obviously was not thought through and had made the situation even worse
than it was before. Two changes after almost reverted it. but a few
leftovers have been left as it. With this revert d3cb25a12138 completely.
While at it,
Kernel doc and the content described by it shouldn't be teared apart.

The warning message did not printed the LCD pixel clock rate but the LCD
clock divisor input rate. As a consequence, the required and real pixel
clock rates are now passed to the tilcdc_pclk_diff().

The tilcdc_pclk_diff() compares the requested pixel clock rate to the
real one, so passing it clk_rate instead of clk_rate / clkdiv caused
it to fail even if the clk_rate was properly set. Adding the

The tab stop for Perl files is by default (at least in emacs) to be 4
spaces, where a tab is used for all 8 spaces. Add a local variable comment
to make vim do the same by default, and this will help keep the file
consistent in the future when others edit it via vi

The __static_call_return0() function is declared to return a 'long',

Hi Marc,

Disable guest access to the Trace Filter control registers.
We do not advertise the Trace filter feature to the guest
(ID_AA64DFR0_EL1: TRACE_FILT is cleared) already, but the guest
can still access the TRFCR_EL1 unless we trap it.
This will

gcc warns about a couple of instances in which a sanity check
exists but the author wasn't sure how to react to it failing,
which makes it look like a possible bug:

Skylake has a mode where the system administrator can use a BIOS setup
option to request that the memory controller report uncorrected errors
found by the patrol scrubber as corrected. This results in them being
signalled using CMCI, which is less disruptive than a machine che

This commit adds ACPI support in the sdhci-of-dwcmshc driver for
BlueField-3 SoC. It has changes to only use the clock hierarchy
for Deviec Tree since the clk is not supported by ACPI. Instead,
ACPI can define 'clock-frequency' which is parsed by existing
sdhci_get_property(). This clock value will
