From 4dc3883203736dcd979672ac8d9f086dbd4d2140 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 8 Jul 2022 21:23:56 +0200 Subject: [PATCH] firmware: ti_sci: Use the non-atomic bitmap API when applicable Usages of the 'res_map' bitmap is protected with a spinlock, so non-atomic functions can be used to set/clear bits.
