Subject: linux-next: build failure after merge of the sound tree
Date: Mon, 20 Jan 2025 14:56:17 +1100 [thread overview]
Message-ID: <20250120145617.07945574@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 1775 bytes --]
Hi all,
After merging the sound tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
sound/usb/fcp.c: In function 'fcp_hwdep_init':
sound/usb/fcp.c:889:22: error: assignment to 'long int (*)(struct snd_hwdep *, char *, long int, loff_t *)' {aka 'long int (*)(struct snd_hwdep *, char *, long int, long long int *)'} from incompatible pointer type 'ssize_t (*)(struct snd_hwdep *, char *, long int, loff_t *)' {aka 'int (*)(struct snd_hwdep *, char *, long int, long long int *)'} [-Wincompatible-pointer-types]
889 | hw->ops.read = fcp_hwdep_read;
| ^
Caused by commit
46757a3e7d50 ("ALSA: FCP: Add Focusrite Control Protocol driver")
I have applied the following patch for today.
