ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). This is less verbose. Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Acked-by: Parthiban Veerasooran <parthiban.veerasooran@xxxxxxxxxxxxx> --- This patch has been sent about 6 months ago [1]. A gentle reminder has been sent 2 months later and an A-by has been given [2]. Another gentle reminder has been sent another 2 months later [3]. However, it has still not reached -next since then in the last 2 months. So, I've added the A-b tag and I'm adding Andrew Morton in To:, in order to help in the merge process.
