X-Git-Tag: accepted/tizen/unified/20230118.172025~7074^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=90c4d05780d47e14a50e11a7f17373104cd47d25;p=platform%2Fkernel%2Flinux-rpi.git usb: fix various gadgets null ptr deref on 10gbps cabling. This avoids a null pointer dereference in f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm} by simply reusing the 5gbps config for 10gbps.
