From d887ae3247e022183f244cb325dca1dfbd0a9ed0 Mon Sep 17 00:00:00 2001 From: Minghao Chi Date: Fri, 13 May 2022 08:19:18 +0000 Subject: octeontx2-pf: Remove unnecessary synchronize_irq() before free_irq() Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way), before any state associated with the IRQ is freed.
