Subject: [PATCH v2] Staging: greybus: Cleanup in greybus driver
Date:   Tue, 16 Apr 2019 17:13:18 -0500
Message-Id: <20190416221318.21161-1-madhumithabiw@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Fix a blank line after structure declarations. Also, convert
macros into inline functions in order to maintain Linux kernel
coding style based on which the inline function is
preferable over the macro.

Blank line fixes are suggested by checkpatch.pl

Signed-off-by: Madhumitha Prabakaran <madhumithabiw@gmail.com>

Changes in v2:
- To maintain consistency in driver greybus, all the instances of macro
with container_of are fixed in a single patch.
