Subject: [PATCH] csky: Fix a size determination in gpr_get()
Date: Tue, 22 Sep 2020 17:15:05 +0800 [thread overview]
Message-ID: <20200922091505.471-1-zhenzhong.duan@gmail.com> (raw)
"*" is missed in size determination as we are passing register set
rather than a pointer.
Fixes: dcad7854fcce ("sky: switch to ->regset_get()")
