| Subject: ACPI: HMAT: remove unnecessary variable initialization |
| |
| From: Vishal Verma <vishal.l.verma@intel.com> |
| |
| [ Upstream commit 14f16d47561ba9249efc6c2db9d47ed56841f070 ] |
| |
| In hmat_register_target_initiators(), the variable 'best' gets |
| initialized in the outer per-locality-type for loop. The initialization |
| just before setting up 'Access 1' targets was unnecessary. Remove it. |
