[PATCH V2 6/9] i2c: xiic: Remove interrupt enable/disable in Rx path

From: Manikanta Guntupalli
Date: Thu Sep 22 2022 - 04:47:32 EST


From: Raviteja Narayanam <raviteja.narayanam@xxxxxxxxxx>

'DYNAMIC_MODE_READ_BROKEN_BIT' quirk added in the driver,
effected IP versions no longer enter dynamic mode.
So, remove local_irq_save/local_irq_restore APIs from driver.
