Subject: [PATCH] cpuidle: Drop unnecessary type cast in cpuidle_poll_time()
Date: Wed, 11 Dec 2019 11:30:50 +0100	[thread overview]
Message-ID: <9680649.eAqxiQ8Vpk@kreacher> (raw)

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The data type of the target_residency_ns field in struct cpuidle_state
is u64, so it does not need to be cast into u64.

Get read of the unnecessary type cast.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
