Lv Yunlong 076de75de1 mtd: rawnand: gpmi: Fix a double free in gpmi_nand_init ... If the callee gpmi_alloc_dma_buffer() failed to alloc memory for this->raw_buffer, gpmi_free_dma_buffer() will be called to free this->auxiliary_virt. But this->auxiliary_virt is still a non-NULL and valid ptr. Then gpmi_alloc_dma_buffer() returns err and gpmi_free_dma_buffer() is called again to free this->auxiliary_virt in err_out. This causes a double free. As gpmi_free_dma_buffer() has already called in gpmi_alloc_dma_buffer's error path, so it should return err directly instead of releasing the dma buffer again.
