Subject: drivers/staging/crystalhd/crystalhd_lnx.c: adjust inconsistent IS_ERR and PTR_ERR
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=45145f9ab143727335477570b436c464880714c8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drivers/staging/crystalhd/crystalhd_lnx.c: adjust inconsistent IS_ERR and PTR_ERR

Change the call to PTR_ERR to access the value just tested by IS_ERR.

The semantic match that finds this problem is as follows:

// <smpl>

expression e,e1;

(
if (IS_ERR(e)) { ... PTR_ERR(e) ... }

if (IS_ERR(e=e1)) { ... PTR_ERR(e) ... }
|
*if (IS_ERR(e))
 { ...
*  PTR_ERR(e1)
   ... }
)
// </smpl>
