Subject: Driver-Core: require valid action string in uevent trigger
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f5468c9ae293cbca43e4ffe6ca3b3235189042a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Driver-Core: require valid action string in uevent trigger

No longer fall back to "add" and warn, but always require a valid
action-string written to the "uevent" file.
