The patch titled Subject: drivers/pps/clients/pps-gpio.c: use devm_kzalloc has been removed from the -mm tree. Its filename was drivers-pps-clients-pps-gpioc-use-devm_kzalloc.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Julia Lawall <Julia.Lawall@xxxxxxx> Subject: drivers/pps/clients/pps-gpio.c: use devm_kzalloc devm_kzalloc allocates memory that is released when a driver detaches. This patch uses devm_kzalloc for data that is allocated in the probe function of a platform device and is only freed in the remove function.
