From: Nathan Fontenot Date: Thu, 30 Mar 2017 06:49:18 +0000 (-0400) Subject: ibmvnic: Merge the two release_sub_crq_queue routines X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b510888f9639588d30d48eaaa32502cdb1c9e9e0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ibmvnic: Merge the two release_sub_crq_queue routines Keeping two routines for releasing sub crqs, one for when irqs are not initialized and one for when they are, is a bit of overkill. Merge the two routines to a common release routine that will check for an irq and release it if needed. Signed-off-by: Nathan Fontenot Signed-off-by: David S.
