header cleaning: don't include smp_lock.h when not used

2007-05-08T18:15:07+00:00

Remove includes of where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs). Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mark struct file_operations const 3

2007-02-12T17:48:45+00:00

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

i2c: Refactor a kfree in i2c-dev

2006-12-10T20:21:33+00:00

Refactor kfree(i2c_dev) into return_i2c_dev(). This saves some code and makes more sense, as the memory is allocated in get_free_i2c_dev(). Signed-off-by: Jean Delvare Cc: Greg Kroah-Hartman

i2c: Fix return value check in i2c-dev

2006-12-10T20:21:33+00:00

device_create() returns error code as pointer on failures. This patch checks the return value of device_create() by using IS_ERR(). Signed-off-by: Akinobu Mita Cc: Greg Kroah-Hartman Signed-off-by: Jean Delvare

i2c: Whitespace cleanups

2006-12-10T20:21:31+00:00

Remove extraneous whitespace from various i2c headers and core files, like space-before-tab and whitespace at end of line. Signed-off-by: David Brownell Signed-off-by: Jean Delvare

i2c: Use put_user instead of copy_to_user where possible

2006-12-10T20:21:30+00:00

This speeds up the I2C_FUNCS ioctl by 5 to 8% in my tests. Signed-off-by: Jean Delvare Laughed-at-by: Mark M. Hoffman

[PATCH] struct path: convert i2c-drivers

I2C: convert i2c-dev to use struct device instead of struct class_device

2006-12-01T22:51:59+00:00

As class_device is going away eventually... Cc: Jean Delvare Signed-off-by: Greg Kroah-Hartman

i2c-dev: attach/detach_adapter cleanups

2006-09-26T22:38:51+00:00

i2c-dev: attach/detach_adapter cleanups * Only print that an adapter was attached when it succeeds. * i2c_dev == NULL on detach simply means that the attach failed before, this isn't an error per se. Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

i2c: __must_check fixes, i2c-dev

2006-09-26T22:38:50+00:00

i2c: __must_check fixes (i2c-dev) Check for error on sysfs file creation. Check for error on device creation. Delete sysfs file on device destruction. I couldn't test this one beyond compilation, as it applies on top of another patch in Greg's tree [1] which breaks all my systems when I apply it (my udev isn't recent enough.) Anyone with bleeding edge udev is welcome to test and report.
