Subject: [PATCH] scsi: ufs-qcom: Make structure ufs_hba_qcom_vops constant
Date: Mon, 19 Aug 2019 13:25:57 +0530	[thread overview]
Message-ID: <20190819075557.1547-1-nishkadg.linux@gmail.com> (raw)

Static structure ufs_hba_qcom_vops, of type ufs_hba_variant_ops, is used
only once, when it is passed as the second argument to function
ufshcd_pltfrm_init(). In the definition of ufshcd_pltfrm_init(), its
second parameter (corresponding to ufs_hba_qcom_vops) is declared as
constant. Hence declare ufs_hba_qcom_vops itself constant as well to
protect it from unintended modification.
Issue found with Coccinelle.
