[PATCH -next] iio/magnetometer: fix AK09911 dependencies

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix AK09911 dependencies to eliminate these build errors (since
'select' does not follow dependencies):

Hi Randy,

Thanks, Arnd Bergman got their first.  Unfortunately I failed to apply before
sending the pull request on to Greg.  Will follow this up asap...
(which might not be that quick as I'm travelling until the weekend).
