| |
Older compilers either want two extra pairs of curly braces around the initializer for local variable "desc", or they want a single pair of curly braces with nothing inside. Current Linux-kernel practice favors the latter, so this commit makes it so.
This is a fix for a regression introduced into v5.6-rc1.
