[PATCH] driver core: location: Free struct acpi_pld_info *pld before return false

From: Hanjun Guo
Date: Tue Nov 22 2022 - 02:53:45 EST


struct acpi_pld_info *pld should be freed before the return of allocation
failure, to prevent memory leak, add the ACPI_FREE() to fix it.

Fixes: bc443c31def5 ("driver core: location: Check for allocations failure")
