Subject: fw_env: fix type of len
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3779c8e319bd5e3fb32c3036cc0d3a658f920fa3;p=u-boot.git

fw_env: fix type of len

This variable is assigned by a size_t, and is printed that way, but is
incorrectly declared as an int.  Which means we get warnings:
fw_env.c: In function 'fw_setenv':
fw_env.c:409:5: warning: format '%zu' expects argument of type 'size_t',
	but argument 3 has type 'int' [-Wformat]
