From a69c5196d20d136b1de120f0fa5ea1e06c3776da Mon Sep 17 00:00:00 2001 From: Anastasia Klimchuk Date: Tue, 6 Jul 2021 16:18:44 +1000 Subject: spi_master: Use new API to register shutdown function This allows spi masters to register shutdown function in spi_master struct, which means there is no need to call register_shutdown in init function, since this call is now a part of register_spi_master. As a consequence of using new API, two things are happening here: 1) No resource leakage anymore in case register_shutdown() would fail, 2) Fixed propagation of register_spi_master() return values. Basic testing: when I comment out free(data) in linux_spi_shutdown, test fails with error ../linux_spi.c:235: note: block 0x55a4db276510 allocated here ERROR: linux_spi_init_and_shutdown_test_success leaked 1 block(s) Means, shutdown function is invoked. BUG=b:185191942 TEST= 1) builds and ninja test including CB:56911 2) On ARMv7 device flashrom -p linux_spi -V -> using linux_spi, chip found 3) On x86_64 AMD device flashrom -p internal -V -> this is actually using sb600spi, chip found Change-Id: Ib60300f9ddb295a255d5ef3f8da0e07064207140 Signed-off-by: Anastasia Klimchuk Reviewed-on: https://review.coreboot.org/c/flashrom/+/56103 Tested-by: build bot (Jenkins) Reviewed-by: Nico Huber Reviewed-by: Angel Pons Reviewed-by: Edward O'Callaghan --- ch341a_spi.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) (limited to 'ch341a_spi.c') diff --git a/ch341a_spi.c b/ch341a_spi.c index 22c97813c..4a7628637 100644 --- a/ch341a_spi.c +++ b/ch341a_spi.c @@ -417,6 +417,7 @@ static const struct spi_master spi_master_ch341a_spi = { .read = default_spi_read, .write_256 = default_spi_write_256, .write_aai = default_spi_write_aai, + .shutdown = ch341a_spi_shutdown, }; static int ch341a_spi_init(void) @@ -505,10 +506,7 @@ static int ch341a_spi_init(void) if ((config_stream(CH341A_STM_I2C_100K) < 0) || (enable_pins(true) < 0)) goto dealloc_transfers; - register_shutdown(ch341a_spi_shutdown, NULL); - register_spi_master(&spi_master_ch341a_spi, NULL); - - return 0; + return register_spi_master(&spi_master_ch341a_spi, NULL); dealloc_transfers: for (i = 0; i < USB_IN_TRANSFERS; i++) { -- cgit v1.2.3
