[U-Boot] [PATCH] usb gadget: increase envstr size in cb_getvar

[Nicolas le bayon]

Hi,

I propose you this patch in order to take into account strings larger than
actual size (32). I recently faced to 'fastboot.partition-type:userdata'
(it was in Android context) but this could be the case for other purposes.

I propose to simply double the size. Is it ok for you?

Regards
