Subject: xilinx: zynqmp: Remove one static variable
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=ced4d46626b06298d19e61279f49bf5158c5e2a6;p=u-boot.git

xilinx: zynqmp: Remove one static variable

There is no reason to have name variable saved in BSS section when it
doesn't need to be really used. That's why remove static from variable
definition and use strdup() to duplicate string with exact size from malloc
area instead.
