Request_region should be used with release_region, not release_resource. The changes are somewhat complicated, so I have only done a few cases to start with. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,E; @@ ( *x = request_region(...) | *x = request_mem_region(...) ) ... when != release_region(x) when != x = E * release_resource(x); // </smpl> The complete set of files in which this semantic match finds problesm is as follows: arch/unicore32/kernel/rtc.c arch/x86/pci/direct.c drivers/char/hw_random/omap-rng.c drivers/char/pcmcia/ipwireless/main.c drivers/i2c/busses/i2c-au1550.c drivers/i2c/busses/i2c-nuc900.c drivers/i2c/busses/i2c-s3c2410.c drivers/i2c/busses/i2c-sh7760.c drivers/i2c/busses/i2c-simtec.c drivers/media/video/s5p-fimc/fimc-core.c drivers/mfd/sm501.c drivers/misc/atmel_tclib.c drivers/mmc/host/au1xmmc.c drivers/mmc/host/davinci_mmc.c drivers/mmc/host/mvsdio.c drivers/mmc/host/pxamci.c drivers/mmc/host/sdhci-s3c.c drivers/mtd/maps/ceiva.c drivers/net/a2065.c drivers/net/ariadne.c drivers/net/arm/ixp4xx_eth.c drivers/net/ax88796.c drivers/parport/parport_ax88796.c drivers/parport/parport_pc.c drivers/rtc/rtc-s3c.c drivers/spi/au1550_spi.c drivers/spi/spi_s3c24xx.c drivers/tty/serial/sh-sci.c drivers/tty/serial/vr41xx_siu.c drivers/usb/gadget/s3c-hsotg.c drivers/video/s3c-fb.c drivers/video/s3c2410fb.c drivers/video/sh7760fb.c drivers/video/sm501fb.c drivers/watchdog/davinci_wdt.c drivers/watchdog/max63xx_wdt.c drivers/watchdog/pnx4008_wdt.c drivers/watchdog/s3c2410_wdt.c -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
