Subject: [PATCH] media: rockchip: rkisp1: use device name for debugfs subdir name
Git-commit: c2611e479f5d9b05108270e1ab423955486b4457
Patch-mainline: v5.17-rc1
References: git-fixes
While testing Rockchip RK3399 with both ISPs enabled, a dmesg error
was observed:
```
[ 15.559141] debugfs: Directory 'rkisp1' with parent '/' already present!
```
Fix it by using the device name for the debugfs subdirectory name
instead of the driver name, thus preventing name collision.
