Subject: optee: Replace uninitialized return variable by proper one.
X-Git-Tag: v2020.04-rc2~23^2~8
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0f97e923d4921a057e1a7bbfac170cadefde5624;p=oweals%2Fu-boot.git

optee: Replace uninitialized return variable by proper one.

As hinted by GCC 9, there is a return statement that returns
an uninitialized variable in optee_copy_firmware_node().
This patch addresses this.
