If anyone has any objections, please let me know. ------------------ From: Lukas Bulwahn [ Upstream commit afcc4e32f606dbfb47aa7309172c89174b86e74c ] As commit 6920b3913235 ("ext4: add new helper interface ext4_try_to_trim_range()") moves some code into the separate function ext4_try_to_trim_range(), the use of the variable ret within that function is more limited and can be adjusted as well. Scope the use of the variable ret locally and drop dead assignments. No functional change.
