Add function helper, fb_is_primary_device(). Given struct fb_info, it will
return a nonzero value if the device is the primary display.
Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.

trident_write_voice_regs() was getting called with the card spinlock held in
only some cases. Fix it.
Explanation: we allocate a new virtual channel in open, and then we frob some
hardware registers (in write_voice_regs) for that channel. But the hardware
registers are shared with other channels, which may be trying to frob the some
registers (albeit for another channel) via ioctl(SNDCTL_DSP_SPEED).

works by Alexander Bigga <ab@mycable.de> who wrote the original
rtc-m41txx.c based on drivers/i2c/chips/m41t00.c driver.
This driver supports M41T8[0-4] and M41ST8[457]. The old m41t00 driver
supports M41T00, M41T81 and M41T85(M41ST85). While the M41T00 chip is now
supported by rtc-ds1307 driver, this driver does not include support for
the chip.

- Make the driver name (and its module alias) match what

Verified on an OMAP H4 development platform, along with a board
init patch to declare its rv5c387a device.
Only one defconfig -- powerpc/linkstation -- uses this driver; but
several other platforms use it, just without defconfig support.
Such platforms need to be converted so (a) their I2C adapter driver
supports new-style drivers, and (b) board init code declares this
I2C device.

This updates the rtc-ds1307 driver so that converting it to a "new style"
driver (driver model, not legacy i2c model) will involve fewer changes.
- Use pointer to i2c_client almost everywhere, so that it's easy
to let the i2c core create that object;
- Avoid using i2c_client.adapter, since that field is redundant and
thus may go away (same object as i2c_client.dev.parent).
- Extend type enum to include various RTCs this is expected to
work with, and include register support for them.
It also cleans up the support for multiple chip types, and fixes a
glitch that could appear with an un-initialized RTC.
