[PATCH v2 -next] platform/x86: intel-ips: fix 'passing zero to PTR_ERR()' warning

From: YueHaibing
Date: Mon Nov 26 2018 - 08:20:10 EST


Fix a static code checker warning:
drivers/platform/x86/intel_ips.c:1314
ips_debugfs_init() warn: passing zero to 'PTR_ERR'
drivers/platform/x86/intel_ips.c:1328
ips_debugfs_init() warn: passing zero to 'PTR_ERR'

If error occurs,debugfs_create_dir/debugfs_create_file
return NULL while debugfs is enabled, which should not
passing to PTR_ERR.

Fixes: aa7ffc01d254 ("x86 platform driver: intelligent power sharing driver")
