From a8ae15ead9c9d10671c3f76cb0749dec6e571ce7 Mon Sep 17 00:00:00 2001 From: Alviro Iskandar Setiawan Date: Tue, 15 Mar 2022 00:18:48 +0000 Subject: [PATCH] ASoC: atmel: mchp-pdmc: Fix `-Wpointer-bool-conversion` warning In function mchp_pdmc_af_put(), Intel's kernel test robot reports the following warning: sound/soc/atmel/mchp-pdmc.c:186:34: warning: address of array \ 'uvalue->value.integer.value' will always evaluate to 'true' \ [-Wpointer-bool-conversion] This is because we are using `uvalue->value.integer.value` which its type is `long value[128];` for conditional expression and that array will always decay to a non-NULL pointer. Using a non-NULL pointer for conditional expression will always evaluate to true. Fix this by changing it to `uvalue->value.integer.value[0]` as that's what the mchp_pdmc_af_get() function sets.
