Subject: ANDROID: input: keychord: Fix for a memory leak in keychord.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=29be5c0c2ef587e7958ef16cc8357e8880e92cd9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ANDROID: input: keychord: Fix for a memory leak in keychord.

Fixes a steady memory leak in the keychord release code. A close of
the keychord device will leak 1 keychord structure. Easily
reproducible by a simple program that does an open()->write()->close()
of the keychord device.
