Subject: Why isn't IRQ shared for i2c-ocore
Date: Wed, 6 May 2015 14:41:31 -0700 [thread overview]

Lee,
I have a follow up question regarding interrupt. I see many I2C bus drivers
request interrupt with flag = 0. Why not using IRQF_SHARED?
I understand the performance concern. If there is any other reason, I want to
know about it before I go too far on my driver.
