6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Su Hui <suhui@xxxxxxxxxxxx>
[ Upstream commit 39b13dce1a91cdfc3bec9238f9e89094551bd428 ]
Clang static checker(scan-build) throws below warning：
| drivers/firmware/arm_scmi/driver.c:line 2915, column 2
| Attempt to free released memory.
When devm_add_action_or_reset() fails, scmi_debugfs_common_cleanup()
will run twice which causes double free of 'dbg->name'.
Remove the redundant scmi_debugfs_common_cleanup() to fix this problem.
Fixes: c3d4aed763ce ("firmware: arm_scmi: Populate a common SCMI debugfs root")
