To: James Simmons, Andrew Morton; +Cc: linux-kernel
The patch below removes kernel 2.2 code from pm3fb.{c,h}.
It also removes KERNEL_2_4 and KERNEL_2_5 since all places where this
was used had a
#if (defined KERNEL_2_4) || (defined KERNEL_2_5)

* [2.6 patch] pm3fb: remove kernel 2.2 code
@ 2005-02-11 16:43 Adrian Bunk
0 siblings, 0 replies; 4+ messages in thread
From: Adrian Bunk @ 2005-02-11 16:43 UTC (permalink / raw)
To: Andrew Morton; +Cc: adaplas, linux-fbdev-devel, linux-kernel
This patch removes kernel 2.2 code from pm3fb.{c,h}.
It also removes KERNEL_2_4 and KERNEL_2_5 since all places where this
was used had a
#if (defined KERNEL_2_4) || (defined KERNEL_2_5)
(Yes, I know the driver is marked as BROKEN.)
