Subject: HID: wacom - request tool info only when we get general events
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=599b082095432f083da89ff53d95b4a878e1fca1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

HID: wacom - request tool info only when we get general events

Move wacom_intuos_schedule_prox_event inside wacom_intuos_general
so we don't call it when general event data isn't ready.
