Subject: media: radio-miropcm20: set bus_info to explicit name
Author: Hans Verkuil <hverkuil-ci...@xs4all.nl>
Date: Sat Sep 23 17:21:05 2023 +0200
Fill in bus_info with fixed name.
This fixes this compiler warning:
drivers/media/radio/radio-miropcm20.c: In function 'vidioc_querycap':
drivers/media/radio/radio-miropcm20.c:206:57: warning: '%s' directive output
may be truncated writing up to 35 bytes into a region of size 28
[-Wformat-truncation=]
206 | snprintf(v->bus_info, sizeof(v->bus_info), "ISA:%s",
dev->v4l2_dev.name);
| ^~
drivers/media/radio/radio-miropcm20.c:206:9: note: 'snprintf' output between 5
