Subject: [PATCH] PCI: acpiphp_ibm: add __ro_after_init to ibm_apci_table_attr
Date: Mon, 26 Dec 2016 21:06:35 +0530	[thread overview]
Message-ID: <1482766595-12679-1-git-send-email-bhumirks@gmail.com> (raw)

The object ibm_apci_table_attr of type bin_attribute structure is not
modified after getting initialized by ibm_acpiphp_init. Apart from
getting referenced in init it is also passed as an argument to the functions
sysfs_{remove/create}_bin_file but both the arguments are of type const 
struct bin_attribute *. Therefore add __ro_after_init to its declaration.
