Subject: Fix memory initialization in ag7240.c
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=3749decc830c7f53827bcfe0d2ea448a0870e890;p=oweals%2Fu-boot_mod.git

Fix memory initialization in ag7240.c

Only the first sizeof(ptr) bytes were initialized correctly.
This leads to a crash in ag7250_send() if mac->next_tx is uninitialized
(if the memory returned by malloc() is not nulled).
