From 3e9c471525328ba152ecbc8aced417e4a7c7a9c1 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sun, 7 May 2023 01:24:04 +0200 Subject: [PATCH] bcm47xx: 5.15: fix compilation warning for yenta socket patchi Rework the patch to completely disable yenta_probe_irq function. The generated mask is zero by lack due to the fact that probe_irq_mask use a val never initialized. Correctly rework the ifdef to make the function always return 0.
