88PM8607 depends on I2C and MFD_CORE. Since 88PM8607 is built-in

The WM8320 is an integrated power management subsystem providing
voltage regulators, RTC, watchdog and other functionality. The
WM8320 is derived from the WM831x and therefore shares most of
the driver code with the WM831x.

As shown by the previous patch (6698e347: "tty: Fix BKL taken under a
spinlock bug introduced in the BKL split") the BKL removal is prone to
some subtle issues, where removing the BKL in one place may in fact make
a previously nested BKL call the new outer call, and then prone to nasty
deadlocks with other spinlocks.

In general, we should never take the BKL while we're holding a spinlock,
so let's just add a "might_sleep()" to it (even though the BKL doesn't
technically sleep - at least not yet), and we'll get nice warnings the
next time this kind of problem happens during BKL removal.

The fasync path takes the BKL (it probably doesn't need to in fact)
while holding the file_list spinlock.  You can't do that with the kernel
lock: it causes lock inversions and deadlocks.

Leave the BKL over that bit for the moment.
