Subject: ideapad: generate valid key event only
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20a769c1c6671d3b8d18a7358eff15e3dd29e94b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ideapad: generate valid key event only

Otherwise will generate KEY_UNKNOWN on un-listed vpc event,
which means nothing and is hard for user to report the detail
of the event.
