From 3ec1428d7b7c519d757a013cef908d7e33dee882 Mon Sep 17 00:00:00 2001 From: Simon Trimmer Date: Mon, 17 Jun 2024 14:53:38 +0100 Subject: [PATCH] ASoC: cs35l56: Accept values greater than 0 as IRQ numbers IRQ lookup functions such as those in ACPI can return error values when an IRQ is not defined. The i2c core driver converts the error codes to a value of 0 and the SPI bus driver passes them unaltered to client device drivers. The cs35l56 driver should only accept positive non-zero values as IRQ numbers.
