i2c: Refactor a kfree in i2c-dev

2006-12-10T20:21:33Z

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

2006-12-10T20:21:33Z

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

2006-12-10T20:21:31Z

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

2006-12-10T20:21:30Z

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

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

2006-12-01T22:51:59Z

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

i2c-dev: attach/detach_adapter cleanups

2006-09-26T22:38:51Z

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

2006-09-26T22:38:50Z

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.

i2c-dev: Drop the client template

2006-09-26T22:38:50Z

i2c-dev: Drop the client template Drop the i2c-dev client template. This saves about 360 bytes of memory. I got the idea from a similar cleanup Hans-Frieder Vogt made to i2c-nforce2 recently. Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

i2c-dev: Use a list for data storage

2006-09-26T22:38:50Z

i2c-dev: Use a list for data storage Use a list instead of a static array for storing the i2c-dev data. Given that most systems have less than 10 i2c busses, most of the space was wasted, so this saves around 1 kB of memory (2 kB on 64-bit archs.) The drawback is that lookup was in O(1) and is now in O(N), but given that the values of N are always small, I don't think this is a problem.
