[Linux-gpib-general] INES GPIB-PCI board: bugs in ver. 4.3.4 and above

[<tn...@gm...>]

Hello,

Since version 4.3.3, I am having problems with an INES GPIB-PCI board in Debian 11.7 (gcc 10.2.1).
The GPIB communication works fine in ver. 4.3.3, but in all the versions above it (4.3.4 to 4.3.6) the board is unresponsive.
The required drivers are nec7210 and ines, of which the first is unchanged (hence OK). As for ines (linux-gpib-4.3.6/linux-gpib-kernel-4.3.6/drivers/gpib/ines), there are some changes from ver. 4.3.3 (working) to the following ones (not working) - see below.

Please check the modified code and, if possible, make it work again also in versions 4.3.4+
