Compilation errors on gcc 7.3 on arm64 4.4.132 kernel.
I'm trying to build the driver on an arm64 4.4.132 based system using gcc 7.3, but I'm getting the compilation errors as shown below:

Note that I have not been able to make the driver work on arm64. But it's at least compiling, and the above compiles and is functional on x86_64, i.e. the driver loads and I can run test_xtrxll with the same result as 1158c4f.
DKMS build fails on a Linux 6.3.3-surface based system due to a read-only vm_area_struct member.
Hello,
I was trying to install another package which pulled in your DKMS module. The build attempt failed on 6.3.3-surface but succeeded on 6.2.10-surface. So I assume the issue is caused by a change in the upstream kernel sources between 6.2.10 and 6.3.3.
dkms console output:

EspressoBin (aarch64): SPI IRQ error 11 (3)
Hello,
I am attempting to run XTRX with Marvell EspressoBin, which uses an Armada 3720 SoC. I built xtrx.ko with the workarounds mentioned in #5 with the following results:

Any thoughts on why the SPI IRQ error might be occurring? I will double-check that the device tree registers interrupts properly. The following is a lot of hopefully helpful diagnostic information:

When I process the data I see a number of issues every so often - so I'm expecting the errors above cause a glitch in the output data stream.
This is running on an old'ish i7 writing to a SSD running Debian unstable. I can do the same capture on a LimeSDR on USB3 on the same machine with no issues.
The script I'm running to do the capture is:
#!/bin/bash
dt=`date -u "+%Y%m%d_%H%M%S"`
freq=1574.92
srate=4000
rx_sdr -d driver=xtrx -f ${freq}M -F CS16 -N2 --gain0 90 --gain1 90 -n 4000M -A LNAH -B3.5M -s 4M gps_xtrx_${dt}_4000_${freq}_ch0.ci16 gps_xtrx_${dt}_4000_${freq}_ch1.ci16
and the rx_sdr program can be found here
Thanks,
Matt

}Timer API changes at some point
This allows to build with the newer timer API which has been in the kernel for a while.
And so this re-enabled the disabled uart_timer code.
Patch both in attachement and inline.
