Subject: [PATCH] drivers : i2c: Allow i2c devices share an interrupt
Date: Tue, 12 Jan 2016 16:01:47 +0800 [thread overview]
Message-ID: <1452585707-20294-1-git-send-email-ying.zhang22455@nxp.com> (raw)
From: Ying Zhang <b40530@freescale.com>
The I2C devices on I2C1, I2C2, I2C3, I2C4 share interrupts,
but the flag is not set when requesting IRQ.
This patch set the flag to IRQF_SHARED.
