init dynamic bin_attribute structures

2010-03-15T03:28:39+00:00

Commit 6992f5334995af474c2b58d010d08bc597f0f2fe ("sysfs: Use one lockdep
class per sysfs attribute.") introduced this requirement.  First, at25
was fixed manually.  Then, other occurences were found with coccinelle
and the following semantic patch.  Results were reviewed and fixed up:

    @ init @
    identifier struct_name, bin;
    @@

    	struct struct_name {
    		...
    		struct bin_attribute bin;
    		...
    	};

    @ main extends init @
    expression E;
    statement S;
    identifier name, err;
    @@

    (
    	struct struct_name *name;
    |
    -	struct struct_name *name = NULL;
    +	struct struct_name *name;
    )
    	...
    (
    	sysfs_bin_attr_init(&name->bin);
    |

    	if (sysfs_create_bin_file(E, &name->bin))
    		S

    	err = sysfs_create_bin_file(E, &name->bin);
    )

i2c: Drop I2C_CLIENT_INSMOD_1

2009-12-14T20:17:26+00:00

This macro simply declares an enum, so drivers might as well declare
it themselves.

i2c: Get rid of struct i2c_client_address_data

2009-12-14T20:17:25+00:00

Struct i2c_client_address_data only contains one field at this point,
which makes its usefulness questionable. Get rid of it and pass simple
address lists around instead.

i2c: Drop the kind parameter from detect callbacks

2009-12-14T20:17:23+00:00

The "kind" parameter always has value -1, and nobody is using it any
longer, so we can remove it.

at24: Use timeout also for read

2009-11-26T08:22:33+00:00

Writes may take some time on EEPROMs, so for consecutive writes, we already
have a loop waiting for the EEPROM to become ready. Use such a loop for reads,
too, in case somebody wants to immediately read after a write. Detailed bug
report and test case can be found here:

max6875: Discard obsolete detect method

2009-10-04T20:53:41+00:00

There is no point in implementing a detect callback for the MAX6875, as
this device can't be detected. It was there solely to handle "force"
module parameters to instantiate devices, but now we have a better sysfs
interface that can do the same.

So we can get rid of the ugly module parameters and the detect callback.
This basically divides the binary module size by 2.

spi: prefix modalias with "spi:"

2009-09-23T14:39:43+00:00

This makes it consistent with other buses (platform, i2c, vio, ...).  I'm
not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.

eeprom/at25: bugfix "not ready" timeout after write

2009-07-30T02:10:35+00:00

Under certain circumstances msleep(1) within the loop, which waits for the
EEPROM to be finished, might take longer than the timeout.  On the next
loop the status register might now return to be ready and therefore the
loop finishes.  The following check now tests if a timeout occurred and if
so returns an error although the device reported it was ready.

This fix replaces testing the occurrence of the timeout by testing the
"not ready" bit in the status register.

i2c/chips: Move max6875 to drivers/misc/eeprom

2009-06-15T16:01:49+00:00

This driver only reads the user EEPROM of that chip, so we can move it
to the eeprom-directory in order to further clean up (and later remove)
drivers/i2c/chips.

The Kconfig text was updated to match the current functionality,
dropping the meanwhile obsoleted parts.

Defconfigs have been adapted.
