Subject: [IRDA]: irlmp_unregister_link() needs to free lsaps.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2638698df30b7b57a8dad7029a0c89fe6c4f6783;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[IRDA]: irlmp_unregister_link() needs to free lsaps.

While testing the mcs7780 based IrDA USB dongle I've stumbled upon
memory leak in irlmp_unregister_link(). Hashbin for lsaps is created in
irlmp_register_link and should probably be freed in irlmp_unregister_link().
