Subject: [PATCH 4.14 01/75] drm/fsl-dcu: avoid disabling pixel clock twice on suspend
Date: Thu, 7 Dec 2017 14:07:23 +0100 [thread overview]
Message-ID: <20171207130818.801986526@linuxfoundation.org> (raw)
In-Reply-To: <20171207130818.742746317@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Agner <stefan@agner.ch>
commit 9306e996574f7f57136a62e49cd0075f85713623 upstream.
With commit 0a70c998d0c5 ("drm/fsl-dcu: enable pixel clock when
enabling CRTC") the pixel clock is controlled by the CRTC code.
Disabling the pixel clock in suspend leads to a warning due to
the second clk_disable_unprepare call:
WARNING: CPU: 0 PID: 359 at drivers/clk/clk.c:594 clk_core_disable+0x8c/0x90
Remove clk_disable_unprepare call for pixel clock to avoid
unbalanced clock disable on suspend.
Fixes: 0a70c998d0c5 ("drm/fsl-dcu: enable pixel clock when enabling CRTC")
