Arguments for sooner: fixes some bad bugs, lower risk as it is
isolated to the w1 driver.

Arguments for later, the bugs aren't new, the first version of the
patch was sent in March and I have yet to get a response from anyone
using the ds1wm master (in some ARM handhelds for battery readings),
maybe if it gets in the merge window someone with the hardware will
actually try it before a kernel release.

I'm fine with either.

I did a quick look, some should be api documentation and updated for
kerneldoc, some clearly aren't.  I'll let Evgeniy Polyakov address
those.

I would have resubmitted it if you had asked, I'm using mutt, which
isn't exactly new or unknown, I guess the incompatibility is why
encryption and signing e-mail hasn't taken taken off as it could have.
There are some problems left in the changelog.

How about one tar.gz?

I did use checkpatch.pl, simple_strtol was the only warning (I ignored
it to be consistent, the fix follows).  strict_strtol is safe here as
it only reads one integer from sysfs.  The patch didn't change,
checkpatch.pl did, I've updated to that as well.


The next set of patches has these minor updates, and checkpatch.pl
returns no errors or warnings.

0005-W1-feature-enable-hardware-strong-pullup.txt
Switch to strict_strtol, code style fixups.

0017-W1-w1_io.c-reset-comments-and-msleep.txt
Fix changelog long lines.

0020-W1-ds2490.c-add-support-for-strong-pullup.txt
Whitespace code style fixups.

0030-W1-ds2490.c-optimize-ds_set_pullup.txt
Whitespace code style fixups.
