Subject: [PATCH v2] drm/msm: Use 64-bit timekeeping
Date: Wed, 13 Apr 2016 02:52:14 -0700	[thread overview]
Message-ID: <20160413095214.GA101605@localhost> (raw)

'struct timespec' uses a 32-bit seconds which will overflow in year
2038 and beyond. This patch replaces timespec with timespec64. The
code is correct as is - the patch is merely part of a larger attempt
to remove all 32-bit timekeeping variables (timespec, timeval, time_t)
from the kernel.
