[PATCH 08/10] i2c: xiic: Remove interrupt enable/disable in Rx path
From: Raviteja Narayanam <hidden>
Date: 2021-05-31 13:29:28
Also in:
linux-arm-kernel, lkml
Subsystem:
arm/zynq architecture, i2c subsystem, i2c subsystem host drivers, the rest · Maintainers:
Michal Simek, Andi Shyti, Linus Torvalds
As the 'DYNAMIC_MODE_READ_BROKEN_BIT' quirk is added in the driver, we no longer enter dynamic mode for the effected IP versions. So, remove local_irq_save/local_irq_restore APIs from driver.
