Subject: [PATCH] spi: set kset of master class dev explicitly
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3bd0f6943520e459659d10f3282285e43d3990f1;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] spi: set kset of master class dev explicitly

<quote Imre Deak from Thu, 12 Jan 2006 21:18:54 +0200>
  In order for spi_busnum_to_master to work spi master devices must be linked
  into the spi_master_class.subsys.kset list.  At the moment the default
  class_obj_subsys.kset is used and we can't enumerate the master devices.
