The PMIC GLINK client stays on the client list until\nits devres release action runs, so a PDR notification can keep queueing\nthe work, and a pending or running worker can access battmgr after devres\nfrees it.\n\nMake enable_work device-managed with devm_work_autocancel(), registered\nbefore the PMIC GLINK client is allocated. The devres cleanup then\nreleases the client first, so no further notification can queue the work,\nand cancels the work before battmgr is freed.\n\nThis issue was found by an in-house static analysis tool."
