Use DEVICE_ATTR_RO() helper macro instead of DEVICE_ATTR(), which makes
the code a bit shorter and easier to read.

This reverts commit 26abfeed43.
In the eisa_probe() force_probe path, if we were unable to request slot
resources (e.g., [io 0x800-0x8ff]), we skipped the slot with "Cannot
allocate resource for EISA slot %d" before reading the EISA signature in
eisa_init_device().
Commit 26abfeed43 moved eisa_init_device() earlier, so we tried to read
the EISA signature before requesting the slot resources, and this caused
hangs during boot.

CC: stable@vger.kernel.org # v3.10+ a2080d0c56: Revert "EISA: Log device resources in dmesg"
We need to give up the last reference to edev->dev, so we need to call
put_device().

Move eisa_init_device() before eisa_request_resources() so the device
name is set before we set up its resources. That way we can print
better messages.
Previously edev->res[i].name was set to NULL in eisa_request_resources(),
then filled in by eisa_init_device(). Now it is filled in by
eisa_init_device() first, and we don't want to clear it out later in
eisa_request_resources().

Previously we marked this as merely IORESOURCE_BUSY without indicating
the type. Setting the type makes %pR on the resource work better.

There is no such thing as a "device name size" in the driver core, so
remove the define and fix up any users of this odd define in the rest of
the kernel.

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.
Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

Add modalias attribute support for the almost forgotten now EISA bus and
(at least some) EISA-aware modules.
The modalias entry looks like (for an 3c509 NIC):
eisa:sTCM5093
and the in-module alias like:
eisa:sTCM5093*
The patch moves struct eisa_device_id declaration from include/linux/eisa.h
to include/linux/mod_devicetable.h (so that the former now #includes the
latter), adds proper MODULE_DEVICE_TABLE(eisa, ...) statements for all
drivers with EISA IDs I found (some drivers already have that DEVICE_TABLE
declared), and adds recognision of __mod_eisa_device_table to
scripts/mod/file2alias.c so that proper modules.alias will be generated.
There's no support for /lib/modules/$kver/modules.eisamap, as it's not used
by any existing tools, and because with in-kernel modalias mechanism those
maps are obsolete anyway.
The rationale for this patch is:
a) to make EISA bus to act as other busses with modalias
support, to unify driver loading
b) to foget about EISA finally - with this patch, kernel
(who still supports EISA) will be the only one who knows
how to choose the necessary drivers for this bus ;)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
