[PATCH 5.4 113/202] ppdev: Remove usage of the deprecated ida_simple_xx() API

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

 



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

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

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit d8407f71ebeaeb6f50bd89791837873e44609708 ]

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.
