[U-Boot] [PATCH] zlib: allow 0 as destination pointer

Dear rhabarber1848,

You are wrong. The urrent code installs WATCHDOG_RESET as s.outcb()
callback; see function zunzip() in "lib_generic/gunzip.c".

I think this is the wrong thing to do. Use the provided callback
instead.


I wonder why you do not create a patch between the old original
version and what wd have in U-Boot now (which should clearly show
what has been changed to adapt this code for U-Boot), and then apply
(if necessary, manually) that patch to the current version?

Best regards,

Wolfgang Denk
