Subject: [patch 1/2] proc_fops: convert drivers/isdn/ to seq_file
From: Alexey Dobriyan <adobriyan@...il.com>
Convert code away from ->read_proc/->write_proc interfaces. Switch to
proc_create()/proc_create_data() which make addition of proc entries
reliable wrt NULL ->proc_fops, NULL ->data and so on.
Problem with ->read_proc et al is described here commit
786d7e1612f0b0adb6046f19b906609e4fe8b1ba "Fix rmmod/read/write races in
/proc entries"
[akpm@...ux-foundation.org: CONFIG_PROC_FS=n build fix]
