[PATCH 0/2] staging: gpib: change return type of t1_delay function to report errors

[Rodrigo Gobbi]

Propagate t1 delay configuration error to userspace
---
Noticed that at [1] there is a FIXME tag to propagate ni_usb_write_registers() 
errors but the t1_delay pointer definition is defined as unsigned int. Checking at
userspace libs, it is possible to notice that the error could be returned/treated in the
following sequence [1], [2] and [3] (I'm simplyfing the codepath here).

The patch is big due the pointer signature change affecting all gpib drivers.
I'm suggesting to return a int value.
I've tested the compilation of every driver after that change.
Tks and regards.
