| * Input: snvs_pwrkey - initialize necessary driver data before enabling IRQAnson Huang2019-04-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | SNVS IRQ is requested before necessary driver data initialized, if there is a pending IRQ during driver probe phase, kernel NULL pointer panic will occur in IRQ handler. To avoid such scenario, just initialize necessary driver data before enabling IRQ. This patch is inspired by NXP's internal kernel tree.

| | * Input: edt-ft5x06 - add support for Evervision FT5726Marco Felsch2019-01-141-3/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Evervision displays are using different Focaltech touchscreen controllers. This commit adds the initial support for the ones using the FT5726 controller. Receiving the touch data is the same as for the GENERIC_FT but the x and y cooridnates are swapped. The main differences are the register addresses where the GAIN and THRESHOLD parameters are stored.

For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
