Subject: adm8211: fix error return code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=72e121191c0b4bde8cd2cea24c0ebc9d70bf8037;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

adm8211: fix error return code

Return a negative error code on failure.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>
