Subject: ACPI-EC: Drop unnecessary check made before calling acpi_ec_delete_query()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4981c2b7abfe92a7ad3c9888b8a1ada552d49406;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ACPI-EC: Drop unnecessary check made before calling acpi_ec_delete_query()

The acpi_ec_delete_query() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
