The patch titled drivers/misc/isl29020.c: don't ignore the i2c_smbus_read_byte_data() return value has been removed from the -mm tree. Its filename was drivers-misc-isl29020c-dont-ignore-the-i2c_smbus_read_byte_data-return-value.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: drivers/misc/isl29020.c: don't ignore the i2c_smbus_read_byte_data() return value From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> If i2c_smbus_read_byte_data() fails, this driver will write a mangled errno value into the hardware.
