From 7a84c636c8ef16465d4ac634b3e613d758b7a975 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 14 Jun 2023 23:06:56 +0200 Subject: net: qca_spi: Avoid high load if QCA7000 is not available [ Upstream commit 92717c2356cb62c89e8a3dc37cbbab2502562524 ] In case the QCA7000 is not available via SPI (e.g. in reset), the driver will cause a high load. The reason for this is that the synchronization is never finished and schedule() is never called. Since the synchronization is not timing critical, it's safe to drop this from the scheduling condition.
