From: Sean Anderson Date: Thu, 1 Feb 2024 18:18:51 +0000 (-0500) Subject: lib: sparse: Fix error checking for write_sparse_chunk_raw X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=766f04a297e892d5106f7f7ac8b43c69bd8a6007;p=u-boot.git lib: sparse: Fix error checking for write_sparse_chunk_raw The return value of write_sparse_chunk_raw is unsigned, so the existing check has no effect. Use IS_ERR_VALUE to detect error instead, which is what write_sparse_chunk_raw does itself.
