From a62385ab803325a27e7ff9981ca644b49de65e2b Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Thu, 21 May 2026 13:56:24 +0530 Subject: [PATCH] lib: sbi_hart: No need to clear features in hart_detect_features() The per-hart features are already zeroed by sbi_scratch_alloc_offset() for all harts so hart_detect_features() should not explicitly clear features later.
