From 8d8fe198c6a756ae96617548af4776e7a86c0d3e Mon Sep 17 00:00:00 2001 From: Cindy H Kao Date: Tue, 18 Aug 2009 19:27:18 -0700 Subject: [PATCH] wimax/i2400m: don't write to memory allocated by request_firmware() In kernel 2.6.31, the firmware requested to ram could be marked with read only attribute, and we can't write any thing directly to the memory when setting up the last JUMP brh cmd. Changed so that the scratch buffer is used.
