commit 9f3c507cb44498067c980674139bcad56e582ee6 upstream.
The commit b1f8921dfbaa ("i2c: amd-asf: Clear remote IRR bit to get successive interrupt") introduced a method to enable successive interrupts but inadvertently omitted the necessary write to the EOI register, resulting in a failure to receive successive interrupts.
Fix this by adding the required write to the EOI register.
