Subject: [PATCH RESEND] HID: sony: Remove usage of the deprecated ida_simple_xx() API
Date: Sun, 14 Apr 2024 11:58:39 +0200
Message-ID: <9b7684381f9d09a7cd5840caa2a160d7764d6403.1713088684.git.christophe.jaillet@wanadoo.fr>

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

This is less verbose.
