Subject: [PATCH 33/34] drivers: remove incorrect of_match_ptr/ACPI_PTR annotations
Date: Wed,  3 Apr 2024 10:06:51 +0200	[thread overview]
Message-ID: <20240403080702.3509288-34-arnd@kernel.org> (raw)
In-Reply-To: <20240403080702.3509288-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

When building with CONFIG_OF and/or CONFIG_ACPI disabled but W=1 extra
warnings enabled, a lot of driver cause a warning about an unused
ID table:

drivers/char/tpm/tpm_ftpm_tee.c:356:34: error: unused variable 'of_ftpm_tee_ids' [-Werror,-Wunused-const-variable]
drivers/dma/img-mdc-dma.c:863:34: error: unused variable 'mdc_dma_of_match' [-Werror,-Wunused-const-variable]
drivers/fpga/versal-fpga.c:62:34: error: unused variable 'versal_fpga_of_match' [-Werror,-Wunused-const-variable]
drivers/i2c/muxes/i2c-mux-ltc4306.c:200:34: error: unused variable 'ltc4306_of_match' [-Werror,-Wunused-const-variable]
drivers/i2c/muxes/i2c-mux-reg.c:242:34: error: unused variable 'i2c_mux_reg_of_match' [-Werror,-Wunused-const-variable]
drivers/memory/pl353-smc.c:62:34: error: unused variable 'pl353_smc_supported_children' [-Werror,-Wunused-const-variable]
drivers/regulator/pbias-regulator.c:136:34: error: unused variable 'pbias_of_match' [-Werror,-Wunused-const-variable]
drivers/regulator/twl-regulator.c:552:34: error: unused variable 'twl_of_match' [-Werror,-Wunused-const-variable]
drivers/regulator/twl6030-regulator.c:645:34: error: unused variable 'twl_of_match' [-Werror,-Wunused-const-variable]
drivers/scsi/hisi_sas/hisi_sas_v2_hw.c:3635:36: error: unused variable 'sas_v2_acpi_match' [-Werror,-Wunused-const-variable]
drivers/staging/pi433/pi433_if.c:1359:34: error: unused variable 'pi433_dt_ids' [-Werror,-Wunused-const-variable]
drivers/tty/serial/amba-pl011.c:2945:34: error: unused variable 'sbsa_uart_of_match' [-Werror,-Wunused-const-variable]

The fix is always to just remove the of_match_ptr() and ACPI_PTR() wrappers
that remove the reference, rather than adding another #ifdef just for build
testing for a configuration that doesn't matter in practice.

I considered splitting up the large patch into per subsystem patches, but since
it's really just the same thing everywhere it feels better to do it all at once.
