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
real_pclk_rate variable makes the code more readable.

LLVM's ld.lld chokes on the 64-bit sign-extended load addresses. Use
32-bit addresses if the linker is LLVM's ld.lld.

The bit mask for MSG_* seems a little confused here. Replace it
with BIT() to make it clear to understand.

In the first patch, I use BIT() for MSG_* to make the code tidier.
Directly use BIT() for MSG_* will be a bit problematic, because
'msg_flags' is defined as 'int' somewhere, and MSG_CMSG_COMPAT
will make it become negative, just like what Guenter Roeck
reported here:

From: Menglong Dong
Currently, MSG_CMSG_COMPAT is defined as '1 << 31'. However, 'msg_flags'
is defined with type of 'int' somewhere, such as 'packet_recvmsg' and
other recvmsg functions:
static int packet_recvmsg(struct socket *sock, struct msghdr *msg,
size_t len,
Abstract: would like to directly set dql.min_limit value inside a
driver to improve BQL performances of a CAN USB driver.
CAN packets have a small PDU: for classical CAN maximum size is
roughly 16 bytes (8 for payload and 8 for arbitration, CRC and
others).
I am writing an CAN driver for an USB i

Add a function to set the dynamic queue limit minimum value.
Some specific drivers might have legitimate reasons to configure
dql.min_limit to a given value. Typically, this is the case when the
PDU of the protocol is smaller than the packet size to used to
carry those frames to the device.
Concr
__must_be_array, offsetof, sizeof_field and __stringify are all
preprocessor macros and do not evaluate their arguments. As such, it
is safe not to warn when arguments are being reused in those four
sub-expressions.
Exclude those so that they can pass checkpatch.

Add support to the reMarkable2 (rM2) for the Wacom I2C device.
This is based on the reMarkable Linux fork and with this series I am
