[PATCH 16/22] iio: imu: Fix dependencies for !HAS_IOMEM archs

[Richard Weinberger]

Not every arch has io memory.
While the driver has correct dependencies the select statement
will bypass the HAS_IOMEM dependency.
So, unbreak the build by rendering it into a real dependency.

Nit: if I parsed the v4.5-rc1 tree correctly I2C_MUX depends I2C. So
just
	depends on I2C_MUX && SYSFS

should also do the trick. Is it clearer to mention both I2C and I2C_MUX
explicitly?

(Likewise for 17/22.)

(evolution 3.16.5 hates replying to plain text messages, so I've lost a
line of context after fiddling with your message here.)

I don't have a strong opinion on that. In general I'm a fan of explicit
dependencies but in this case, you are right, also an implicit one should to it.
Let's see what maintainers think. :-)

Applied to the temporary branch for post 4.5 fixes
(as I haven't unwound that yet) for iio.git.

Applied to the same obscure branch of iio.git as patch 6.
Will unwind this cross merge window mess in my tree sometime
in the next week or so.

I find it hard to care ;)

Anyhow, the version as stands applied to the rather odd fixes-post-4.5rc1 branch
that I currently have in iio.git - will unwind that now we are post said version
sometime in next few days (this on is only there because I needed to take patch
06 through that branch).
