Subject: [PATCH -next] bcache: Fix spelling mistakes and cleanup code
Date:   Fri, 15 Jul 2022 15:15:33 +0800
Message-Id: <20220715071533.2729413-1-williamsukatube@163.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

From: William Dean <williamsukatube@gmail.com>

First, fix follow spelling misktakes:
	automatical  ==> automatic
	individial  ==> around
	embeddded  ==> embedded
	addionally  ==> addtionally
	unncessary  ==> unnecessary
	definitly  ==> definitely
Second, delete extra space or tab where
appropriate to make code format more standardized.
