Error string and comment say we fall back to a default, but in reality
we bailed out. Refactor the code to use the core helper which then
matches the described behaviour. While updating the init message anyhow,
shorten it while we are here; no need for versioning there as well and
the name is already given via pr_fmt.

On mips and parisc:
drivers/bluetooth/btwilink.c: In function 'ti_st_open':
drivers/bluetooth/btwilink.c:174:21: warning: overflow in implicit constant conversion [-Woverflow]
hst->reg_status = -EINPROGRESS;
drivers/nfc/nfcwilink.c: In function 'nfcwilink_open':
drivers/nfc/nfcwilink.c:396:31: warning: overflow in implicit constant conversion [-Woverflow]
drv->st_register_cb_status = -EINPROGRESS;
There are actually two issues:
1. Whether "char" is signed or unsigned depends on the architecture.
As the completion callback data is used to pass a (negative) error
code, it should always be signed.
2. EINPROGRESS is 150 on mips, 245 on parisc.
Hence -EINPROGRESS doesn't fit in a signed 8-bit number.
Change the callback status from "char" to "int" to fix these.

Add a new read function to the at24 driver allowing to retrieve the
factory-programmed mac address embedded in chips from the at24mac
family.
These chips can be instantiated similarily to the at24cs family,
except that there's no way of having access to both the serial number
and the mac address at the same time - the user must instantiate
either an at24cs or at24mac device as both special memory areas are
accessible on the same slave address.

The chips from the at24cs family have two memory areas - a regular
read-write block and a read-only area containing the serial number.
The latter is visible on a different slave address (the address of the
rw memory block + 0x08). In order to access both blocks the user needs
to instantiate a regular at24c device for the rw block address and a
corresponding at24cs device on the serial number block address.
Add a function that allows to access the serial number and assign it
to at24->read_func if the chip allows serial number read operations
and the driver was passed the relevant flag for this device.

Split at24_eeprom_write() into three smaller functions - one for the
i2c operations and two for the smbus extensions (separate routines for
block and byte transfers). Assign them in at24_probe() depending on
the bus capabilities.
Also: in order to avoid duplications move code adjusting the count
argument into a separate function and use it for i2c and smbus block
writes (no need for a roll-over for byte writes as we're always
writing one byte).

Before splitting the read/write routines into smaller, more
specialized functions, unduplicate some code in advance.
Use a 'for' loop instead of 'do while' when waiting for the previous
write to complete and hide it behind a macro.

The first step in simplifying the read and write functions is to call
them via function pointers stored in at24_data. When we eventually
split the routines into smaller ones (depending on whether they use
smbus or i2c operations) we'll simply assign them to said pointers
instead of checking the flags at runtime every time we read/write.

The conversion from DocBook required some fixes:
- Now, the C files with the exported symbols also need to be
added. So, all headers need to be included twice: one to
get the structs/enums/.. and another one for the functions;
- Notes should use the ReST tag, as kernel-doc doesn't
recognizes it anymore;
- Identation needs to be fixed, as ReST uses it to identify
when a format "tag" ends.
- Fix the cross-references at the media controller description.

The conversion from DocBook lead into some conversion issues,
basically due to the lack of proper support at kernel-doc.
So, address them:
- Now, the C files with the exported symbols also need to be
added. So, all headers need to be included twice: one to
get the structs/enums/.. and another one for the functions;
- Notes should use the ReST tag, as kernel-doc doesn't
recognizes it anymore;
- Identation needs to be fixed, as ReST uses it to identify
when a format "tag" ends.
- kernel-doc doesn't escape things like *pointer, so we
need to manually add a escape char before it.
- On some cases, kernel-doc conversion requires violating
the 80-cols, as otherwise it won't properly parse the
source code.

total number of members
Currently, sound device drivers for PCI cards produced by Echo Audio
support dimension parameter of element information. But the information
has contradictions to the number of members of each element. I guess that
this comes from the assumption that these sound cards are used only by
'echomixer' in userspace. But ideally, they should be used with usual ALSA
control applications.
This commit removes the contradiction. As a result, 'Monitor Mixer Volume'
and 'VMixer Volume' elements are shown in usual ALSA control applications
such as 'amixer' and 'alsamixer' in series.
