Hi Samuel, After merging the mfd tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/mfd/tps6507x.c: In function 'tps6507x_i2c_probe': drivers/mfd/tps6507x.c:90: error: implicit declaration of function 'kzalloc' drivers/mfd/tps6507x.c:90: warning: assignment makes pointer from integer without a cast drivers/mfd/tps6507x.c:92: error: implicit declaration of function 'kfree' Caused by commit 353dd1bf937f319eb6fdf35a461bf0bea1361d23 ("mfd: Add TPS6507x support"). I applied the following patch for today.
