Subject: Remove NULL check from tui_reg_command
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0f8d8876d98305671a19b5bf88f125d4d02c7e0f;p=binutils-gdb.git

Remove NULL check from tui_reg_command

tui_reg_command has an unnecessary NULL check.  The preceding call to
tui_reg_layout will ensure the window exists.  This patch removes the
check.
