Subject: [PATCH 6/6] net: caif: Fix debugfs on 64-bit platforms
Git-commit: b52517e456f8bb6ae720feab891af6d5b8a8f217
Patch-mainline: v5.5-rc1
References: git-fixes

"ser_device.state" is "unsigned long", i.e. 32-bit or 64-bit, depending
on the platform.  Hence casting its address to "u32 *", and calling
debugfs_create_x32() breaks operation on 64-bit platforms.

Fix this by using the new debugfs_create_xul() helper instead.
