From: Ingo Molnar Date: Sun, 19 Feb 2006 05:22:30 +0000 (-0500) Subject: Input: joysticks - semaphore to mutex conversion X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=72ba9f0ce09c5508ec4b0cf30e88899872a83f75;p=linux-beck.git Input: joysticks - semaphore to mutex conversion The conversion was generated via scripts, and the result was validated automatically via a script as well. Amijoy conversion was done by Arjan van de Ven.
