Subject: [PATCH 22/30] ACPI: OSL: Add missing annotation for acpi_os_acquire_lock()
Sparse reports a warning at acpi_os_acquire_lock()
warning: context imbalance in acpi_os_acquire_lock() - unexpected unlock
The root cause is the missing annotation at acpi_os_acquire_lock()
Add the missing annotation __acquires(lockp)
