I'd > like to take care of them. 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 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 Signed-off-by: Vladimir Zapolskiy Signed-off-by: Wolfram Sang commit 1f023297f7f77d434ecc221018d2e181eac0ae36 Author: Vladimir Zapolskiy 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.
