Subject: [PATCH v2 10/13] net: ethernet: ti: cpts: drop excessive writes to CTRL and INT_EN regs
Date: Mon, 28 Nov 2016 17:03:34 -0600	[thread overview]
Message-ID: <20161128230337.6731-11-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20161128230337.6731-1-grygorii.strashko@ti.com>

CPTS module and IRQs are always enabled when CPTS is registered,
before starting overflow check work, and disabled during
deregistration, when overflow check work has been canceled already.
So, It doesn't require to (re)enable CPTS module and IRQs in
cpts_overflow_check().
