From: Anuj Phogat Date: Thu, 20 Mar 2014 19:16:40 +0000 (-0700) Subject: mesa: Remove redundant if checks in _mesa_texstore_xx_xx() functions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ef924f0de93accff2ea12dbd90cc3c1df794c8f5;p=mesa.git mesa: Remove redundant if checks in _mesa_texstore_xx_xx() functions This patch contains non-functional changes. Assertion checks made earlier in the functions make the if checks redundant. So, remove the if checks and unindent the code in if block.
