spi: spi-mem: Fix a memory leak in spi_mem_dirmap_destroy()
The dirmap descriptor object allocated in spi_mem_dirmap_create is never freed. Add a kfree(desc) in spi_mem_dirmap_destroy(). Fixes: aa167f3fed0c ("spi: spi-mem: Add a new API to support direct mapping") Signed-off-by: Boris Brezillon <bbrezillon@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
