Log Message
Add irq_flags to:
struct spi_board_info
struct i2c_board_info
These flags can be optionally defined - slave drivers may use them as
flags argument for request_irq().
In case they are left un-initialized they will default to zero, and
therefore shouldn't cause problems.
This may avoid unconditional calls from platform init code to
set_irq_type() when SPI/I2C Slave drivers are build as modules.
It also matches behavior of some other frameworks like IDE and UIO.
