[Arm-dev] Issues with the 4.9.x kernel and pvrusb2 driver

[Chris Szilagyi]

I seem to have stumbled upon an issue larger than I thought.  I have 
been fighting this driver in the 4.9.75-204 kernel that is the current 
release for the AltArch/Arm32 platforms.  Basically I'm getting a kernel 
oops with this kernel (I included below).  I have tried patching and 
compiling my own module however I'm now getting a segfault with that.  
It seems that the 4.14 kernel may have resolved this issue:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/media/usb/pvrusb2/pvrusb2-eeprom.c?h=v4.14-rc1&id=446aba663b8240b24202cb8902b0d5c8f91aa3da

But I'm hoping to get this fixed with the 4.9.75 kernel or the 4.9.x 
series if that is what will be used for future kernel updates for this 
platform.  I found a post regarding the issue on an Ubuntu forum and it 
appears this is the same thing I'm getting with this CentOS 4.9.75 kernel:

https://bugs.launchpad.net/ubuntu/+bug/1710419

This is the patch I tried and so far no luck.  If anybody has a way to 
help or any thoughts on how to get this integrated to the kernels for 
this, I am more than happy to test it here on the Banana Pi.

Thank you for your help.

Chris
