As platform_get_irq() now prints an error when the interrupt does not exist, this warnings are printed on bananapi-r2: [ 4.935780] mt6577-uart 11004000.serial: IRQ index 1 not found [ 4.962589] 11002000.serial: ttyS1 at MMIO 0x11002000 (irq = 202, base_baud = 1625000) is a ST16650V2 [ 4.972127] mt6577-uart 11002000.serial: IRQ index 1 not found [ 4.998927] 11003000.serial: ttyS2 at MMIO 0x11003000 (irq = 203, base_baud = 1625000) is a ST16650V2 [ 5.008474] mt6577-uart 11003000.serial: IRQ index 1 not found Fix this by calling platform_get_irq_optional() instead. now it looks like this: [ 4.872751] Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled Fixes:7723f4c5ec("driver core: platform: Add an error message to platform_get_irq*()") Signed-off-by: Frank Wunderlich <frank-w@public-files.de> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20191027062117.20389-1-frank-w@public-files.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
