Subject: [PATCH] ppp: Adjust indentation into ppp_async_input
Date: Mon, 9 Dec 2019 15:38:59 -0700 [thread overview]
Message-ID: <20191209223859.19013-1-natechancellor@gmail.com> (raw)
Clang warns:
../drivers/net/ppp/ppp_async.c:877:6: warning: misleading indentation;
statement is not part of the previous 'if' [-Wmisleading-indentation]
ap->rpkt = skb;
^
../drivers/net/ppp/ppp_async.c:875:5: note: previous statement is here
if (!skb)
^
1 warning generated.
This warning occurs because there is a space before the tab on this
line. Clean up this entire block's indentation so that it is consistent
with the Linux kernel coding style and clang no longer warns.
Fixes: 6722e78c9005 ("[PPP]: handle misaligned accesses")
