Subject: [PATCH v2] drivers/thermal: optimize the for circle to run a bit fast
Date: Mon, 26 Oct 2020 18:37:42 -0700	[thread overview]
Message-ID: <20201027013743.62392-1-bernard@vivo.com> (raw)

Function thermal_zone_device_register, in the for circle, if the
first if branch set the count bit in tz->trips_disabled, there is
no need to set in the other if branch again.
This change is to make the code run a bit fast and readable.

Signed-off-by: Bernard Zhao <bernard@vivo.com>

Changes since V1:
*make the code more clear and readable
