This reverts commit 1028b55baf.
It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.
You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.
I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.
So my track record is not good enough, and the stars will have to align
better before that one gets committed. And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.
IOW, let's just revert the commit that caused the problem for now.

In addition, due to that breakage, Mikulas Patocka noticed that
handling exceptions from modules probably never worked on parisc. It

during normal use.

Core fixes:
- Defer GPIO device setup until after gpiolib is initialized.
It turns out that a few very tightly integrated GPIO platform
drivers initialize so early (befor core_initcall()) so that
the gpiolib isn't even initialized itself. That limits what
the library can do, and we cannot reference uninitialized
fields until later. Defer some of the initialization until
right after the gpiolib is initialized in these (rare) cases.
- As a consequence: do not use devm_* resources when allocating
the states in the initial set-up of the gpiochip.
Driver fixes:
- In ACPI retrieveal: ignore GpioInt when looking for output
GPIOs.
- Fix legacy builds on the PXA without a backing pin controller.
- Use correct datatype on pca953x register writes.
