Subject: [PATCH] drivers/perf: Remove usage of the deprecated ida_simple_xx() API
Date:   Sun, 10 Dec 2023 18:48:18 +0100
Message-Id: <85b0b73a1b2f743dd5db15d4765c7685100de27f.1702230488.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.
