[PATCH 6.10 121/634] spi: ppc4xx: Avoid returning 0 when failed to parse and map IRQ

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

[ Upstream commit 7781f1d120fec8624fc654eda900fc8748262082 ]

0 is incorrect error code when failed to parse and map IRQ.
Replace OF specific old API for IRQ retrieval with a generic
one to fix this issue.
