A single character (depending on a condition check) should be put
into a sequence. Thus use the corresponding function “seq_putc”.
This issue was detected by using the Coccinelle software.

Hi all,

Reading the count register clears the interrupt signal. Currently, the
count registers are read into 'regval' variable but the variable is
never used. Therefore remove it. V2 of this patch add comments to
justify the readl calls without checking the return value.

Fix a crash with multipath activated. It happends when ANA log
page is larger than MDTS and because of that ANA is disabled.
When connecting the target, the driver in nvme_parse_ana_log

On some i.MX8M platforms, clock driver uses platform driver
model and it is NOT ready during timer initialization phase,
the clock operations will fail and system counter driver will
fail too. As all the i.MX8M platforms' system counter clock
are from OSC which is always enabled

Add i.MX8MM system counter node to enable timer-imx-sysctr
broadcast timer driver.

Systems which use platform driver model for clock driver require the
clock frequency to be supplied via device tree when system counter
driver is enabled.
This is necessary as in the platform driver model the of_clk operations
do not work correctly because system counter driver
From: Anson Huang
More and more platforms use platform driver model for clock driver,
so the clock driver is NOT ready during timer initialization phase,
it will cause timer initialization failed.
To support those platforms with upper scenario, introducing a new
flag TIMER_OF_CLOCK_FREQUENCY whi

Architectures like parisc enable CONFIG_KROBES without having a definition
for kprobe_fault_handler() which results in a build failure. Arch needs to
provide kprobe_fault_handler() as it is platform specific and cannot have
a generic working alternative. But in the event when platform lacks such a

We have 3 laptops which connect the wifi by the same RTL8723BU.
The PCI VID/PID of the wifi chip is 10EC:B720 which is supported.
They have the same problem with the in-kernel rtl8xxxu driver, the

Nevertheless, the signal strength is
