This patch set removes the BUG_ON() from hwspinlock core and changes the
PM runtime support to be optional.
Baolin Wang (4):
hwspinlock: Remove BUG_ON() from the hwspinlock core
hwspinlock: Let the PM runtime can be optional
hwspinlock: sprd: Remove redundant PM runtime implementation
hwspinlock: u8500_hsem: Remove redundant PM runtime implementation

The original code use BUG_ON() to validate the parameters when locking
or unlocking one hardware lock, but we should not crash the whole kernel
though the hwlock parameters are incorrect, instead we can return
the error number for users and give some warning.

Now some hwspinlock controllers did not have the requirement to implement
the PM runtime, but drivers must enable the PM runtime to comply with the
hwspinlock core.
Thus we can change the PM runtime support to be optional by validating
the -EACCES error number which means the PM runtime is not enabled, and
removing the return value validating of pm_runtime_put(). So that we
can remove some redundant PM runtime code in drivers.
