Subject: drivers/video/mb862xx/mb862xxfbdrv.c: fix error return code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4aedf566f2804f14586363a234386a3eceb6aeec;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drivers/video/mb862xx/mb862xxfbdrv.c: fix error return code

Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.

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

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>
