From 0fdd07f77fd9cc6a7d49076793daef06ea5d8f13 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 9 Aug 2009 11:42:32 +0200 Subject: VIDEO: Correct use of request_region/request_mem_region request_region should be used with release_region, not request_mem_region. Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c, the problem is actually the other way around; request_mem_region should be used instead of request_region. The semantic patch that finds/fixes this problem is as follows: (http://coccinelle.lip6.fr/) // @r1@ expression start; @@ request_region(start,...) @b1@ expression r1.start; @@ request_mem_region(start,...) @depends on !b1@ expression r1.start; expression E; @@ - release_mem_region + release_region (start,E) // Signed-off-by: Julia Lawall Signed-off-by: Ralf Baechle --- drivers/video/gbefb.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/video/gbefb.c') diff --git a/drivers/video/gbefb.c b/drivers/video/gbefb.c index 1a83709f961..f67db426837 100644 --- a/drivers/video/gbefb.c +++ b/drivers/video/gbefb.c @@ -1147,7 +1147,7 @@ static int __init gbefb_probe(struct platform_device *p_dev) gbefb_setup(options); #endif - if (!request_region(GBE_BASE, sizeof(struct sgi_gbe), "GBE")) { + if (!request_mem_region(GBE_BASE, sizeof(struct sgi_gbe), "GBE")) { printk(KERN_ERR "gbefb: couldn't reserve mmio region\n"); ret = -EBUSY; goto out_release_framebuffer; -- cgit v1.2.3-70-g09d2
