Bluetooth update for 2.6

Hi Dave,

here are some bug fixes for the Bluetooth subsystem. I included the kzalloc cleanup since I saw you still taking these kind of updates.

Regards

Marcel

[Bluetooth] Fix deadlock in the L2CAP layer

The Bluetooth L2CAP layer has 2 locks that are used in softirq context, (one spinlock and one rwlock, where the softirq usage is readlock) but where not all usages of the lock were _bh safe. The patch below corrects this.

[Bluetooth] Let BT_HIDP depend on INPUT

This patch lets BT_HIDP depend on instead of select INPUT. This fixes the following warning during an s390 build:

net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol 'BT_HIDP' refer to undefined symbol 'INPUT'

A dependency on INPUT also implies !S390 (and therefore makes the explicit dependency obsolete) since INPUT is not available on s390.

The practical difference should be nearly zero, since INPUT is always set to y unless EMBEDDED=y (or S390=y).
