Subject: [PATCH for-next 2/7] RDMA/rtrs: Remove len parameter from helper print functions of sysfs
Date: Wed, 22 Sep 2021 14:53:28 +0200	[thread overview]
Message-ID: <20210922125333.351454-3-haris.iqbal@ionos.com> (raw)
In-Reply-To: <20210922125333.351454-1-haris.iqbal@ionos.com>

Since we have changed all sysfs show functions to use sysfs_emit, we do
not require the len (PAGE_SIZE) in our helper print functions. So remove
it from the function parameter.
