Subject: zstd: Fix definition of assert()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=78b342f0cda74f20cea51f0f1e1e9565e3054ffc;p=users%2Fjedix%2Flinux-maple.git

zstd: Fix definition of assert()

[ Upstream commit 6906598f1ce93761716d780b6e3f171e13f0f4ce ]

assert(x) should emit a warning if x is false. WARN_ON(x) emits a
warning if x is true. Thus, assert(x) should be defined as WARN_ON(!x)
rather than WARN_ON(x).
