      "message": "hwspinlock/core: register a bank of hwspinlocks in a single API call\n\nHardware Spinlock devices usually contain numerous locks (known\ndevices today support between 32 to 256 locks).\n\nOriginally hwspinlock core required drivers to register (and later,\nwhen needed, unregister) each lock separately.\n\nThat worked, but required hwspinlocks drivers to do a bit extra work\nwhen they were probed/removed.\n\nThis patch changes hwspin_lock_{un}register() to allow a bank of\nhwspinlocks to be {un}registered in a single invocation.\n\nA new \u0027struct hwspinlock_device\u0027, which contains an array of \u0027struct\nhwspinlock\u0027s is now being passed to the core upon registration (so\ninstead of wrapping each struct hwspinlock, a priv member has been added\nto allow drivers to piggyback their private data with each hwspinlock).\n\nWhile at it, several per-lock members were moved to be per-device:\n1. struct device *dev\n2. struct hwspinlock_ops *ops\n\nIn addition, now that the array of locks is handled by the core,\nthere\u0027s no reason to maintain a per-lock \u0027int id\u0027 member: the id of the\nlock anyway equals to its index in the bank\u0027s array plus the bank\u0027s\nbase_id.\nRemove this per-lock id member too, and instead use a simple pointers\narithmetic to derive it.\n\nAs a result of this change, hwspinlocks drivers are now simpler and smaller\n(about %20 code reduction) and the memory footprint of the hwspinlock\nframework is reduced.\n\nSigned-off-by: Ohad Ben-Cohen \u003cohad@wizery.com\u003e\n"
