Subject[PATCH -next] irq: print depth in __enable_irq WARNING
Date
Since case 0 and 1 of desc->depth may print same warning messages as follows,
according to the messages, we do not know in which case the warning is generated.
This patch prints extra desc->depth in the warning messages to distinguish
these cases.
This patch just does warning message changes,no functional changes.
