PCI device driver broken between 4.2 and 4.3

[Олег Мороз]

Hello. I've got a device driver for MIL-1553b card called TA1-PCI, which could 
be found at
 https://github.com/qmor/elcus-1553-driver-linux
Card is using PLX_PCI9030 PCI controller.
Today i've found that this driver compiles, installes, but is not working as it 
should.
Looks like it not receives any interrupts from PCI. I've test it again with 
kernel
4.2 and it works okay. What changes was made in PCI subsystem from 4.2 to 4.3
which could have impact this driver work.
