if we're talking about this particular series, you should have them in
your mailbox, since you have them applied in wsa/i2c/for-next:

commit d12c0aaf3780c5b26b4ea9e795252381f586c063
Author: Vladimir Zapolskiy <vz@...ia.com>
Date:   Mon Jul 27 00:18:51 2015 +0300

    misc: eeprom: at24: clean up at24_bin_write()

    The change removes redundant sysfs binary file boundary check, since
    this task is already done on caller side in fs/sysfs/file.c

commit 1f023297f7f77d434ecc221018d2e181eac0ae36
Author: Vladimir Zapolskiy <vz@...ia.com>
Date:   Mon Jul 27 00:16:31 2015 +0300

    i2c: slave eeprom: clean up sysfs bin attribute read()/write()

    The change removes redundant sysfs binary file boundary checks,
    since this task is already done on caller side in fs/sysfs/file.c

    Note, on file size overflow read() now returns 0, and this is a
    correct and expected EOF notification according to POSIX.

Do you want me to send them to you again anyway?
