From: Mathias Kresin Date: Thu, 29 Dec 2016 20:47:54 +0000 (+0100) Subject: generic: backport dwc2 kernel panic fix X-Git-Tag: v17.01.0-rc1~323 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=b35a41c139ec995e1d3096ce962f020053f3056e generic: backport dwc2 kernel panic fix In case the soft reset in dwc2_core_reset() timeouts, the hsotg->core_params are freed albeit it is owned by the core. This results into a kernel panic as shown in FS#351.
