CVE-2026-23431

Description

In the Linux kernel, the following vulnerability has been resolved:

spi: amlogic-spisg: Fix memory leak in aml_spisg_probe()

In aml_spisg_probe(), ctlr is allocated by spi_alloc_target()/spi_alloc_host(), but fails to call spi_controller_put() in several error paths. This leads to a memory leak whenever the driver fails to probe after the initial allocation.

Convert to use devm_spi_alloc_host()/devm_spi_alloc_target() to fix the memory leak.
