From c335631a68db4b32b24cb59814c485c45f0f4506 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Mon, 31 Aug 2015 17:31:28 +0300 Subject: i2c: designware: Remove interrupt clearing from i2c_dw_pci_probe() There is no need to clear interrupts in i2c_dw_pci_probe() since only place where interrupts are unmasked is i2c_dw_xfer_init() and there interrupts are always cleared after commit 2a2d95e9d6d2 ("i2c: designware: always clear interrupts before enabling them"). This allows to cleanup the code and replace i2c_dw_clear_int() in i2c_dw_xfer_init() by direct register read as there are no other callers.
