Subject: [PATCH v4 0/9] Add '__adis_enable_irq()'

Added implementation for '__adis_enable_irq()' and called it instead of
'adis_enable_irq()' inside '__adis_initial_startup()'.
Replaced 'adis_initial_startup()' calls in probe, with its unlocked
variant.

changes in v3:
new patches: 1,2
changed commit message for patches 2-9

changes in v4:
squashed patches 1 & 2 from v3

Ramona Bolboaca (9):
