Subject: [LINUX PATCH v2 2/3] spi: spi-mem: export spi_mem_default_supports_op()
Date: Mon, 1 Apr 2019 13:29:00 +0530 [thread overview]
Message-ID: <1554105540-19704-1-git-send-email-naga.sureshkumar.relli@xilinx.com> (raw)
Export spi_mem_default_supports_op(), so that controller drivers
can use this.
spi-mem driver already exports this using EXPORT_SYMBOL,
but not declared it in spi-mem.h.
This patch declares spi_mem_default_supports_op() in spi-mem.h and
also removes the static from the function prototype.
Signed-off-by: Naga Sureshkumar Relli <naga.sureshkumar.relli@xilinx.com>

Changes in v2
- Export spi_mem_default_supports_op(), so that controller drivers
can use it
- Removed the code, which modifies calling spi_mem_default_supports_op()
before calling ctrl->supports_op()
Changes in v1
- None
