Date: Mon, 8 Feb 2021 23:38:07 +0100 Message-Id: <20210208223810.388502-1-bigeasy@linutronix.de> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-omap@vger.kernel.org Folks, in the discussion about preempt count consistency across kernel configurations: https://lore.kernel.org/r/20200914204209.256266093@linutronix.de/ it was concluded that the usage of in_interrupt() and related context checks should be removed from non-core code. In the long run, usage of 'preemptible, in_*irq etc.' should be banned from driver code completely. This series targets the video subsystem. The omap patches are a repost of [0], the amba-clcd is new after I received no feedback on my analysis [1].
